There is a famous saying:

> Explaining a joke is like dissecting a frog. You understand it better but the frog dies in the process.

Nevertheless, that is what I decided to do with ChatGPT. I asked ChatGPT to explain some of my favourite jokes to me. The sections below show how the conversation went. This was one long conversation but I have split it into multiple sections to make the dialogue easy to read.

## Three Pints of Guinness

> Susam: I will share a joke with you. Explain to me why it is funny.

> ChatGPT: Sure! I'd be happy to help you understand why a joke is funny. Please go ahead and share the joke with me.

> Susam: A man walks into a pub and says, "Give me three pints of Guinness, please."

> So the bartender brings him three pints and the man proceeds to alternately sip one, then the other, then the third until they're gone.

> He then orders three more and the bartender says, "Sir, I know you like them cold, so you can start with one and I'll bring you a fresh one as soon as you're low."

> The man says, "You don't understand. I have two brothers, one in Australia and one in the States. We made a vow to each other that every Saturday night we'd still drink together. So right now, my brothers have three Guinness Stouts too and we're drinking together."

> The bartender thinks it's a wonderful tradition and every week he sets up the guy's three beers as soon as he enters in the bar. Then one week, the man comes in and orders only two. He drinks them, then orders two more. The bartender sadly says, "Knowing your tradition, I'd just like to just say that I'm sorry that one of your brothers died."

> The man replies, "Oh, my brothers are fine – I just quit drinking."

> ChatGPT: This joke is funny because it has a surprising punchline. The setup of the joke establishes that the man has a weekly tradition of drinking three pints of Guinness with his two brothers, one in Australia and one in the United States. The bartender assumes that something has happened to one of the brothers when the man only orders two pints, and the man's response that he has quit drinking is unexpected and surprising. The punchline effectively subverts the expectations that the joke has established, leading to a comedic reveal that creates humor.

> Susam: Exactly what about the punchline subverts the expectations?

> ChatGPT: In the setup of the joke, the man's weekly tradition of drinking three pints of Guinness with his two brothers is established. This sets up the expectation that the man will continue to follow this tradition and order three pints each week. However, when the man only orders two pints, the bartender assumes that something has happened to one of the brothers, setting up the expectation that the punchline will be a tragic revelation about the fate of one of the man's brothers. Instead, the punchline reveals that the man has actually quit drinking, which is unexpected and surprising, and effectively subverts the expectations that have been established in the setup of the joke.

I like how ChatGPT mentions that the joke was setting up an expectation that something tragic might have happened to the third brother.

## A Pun Walks Into a Bar

> Susam: Alright, I will share another joke. Will you explain that to me too?

> ChatGPT: Sure! I'd be happy to help you understand why a joke is funny. Please go ahead and share the joke with me.

> Susam: A pun walks into a bar, ten people die on the spot. Pun in, ten dead.

> ChatGPT: This joke is funny because it uses wordplay, or a play on words, to create a punchline that is unexpected and humorous. In this joke, the word "pun" is used in two different ways: first, as a type of joke that relies on wordplay, and second, as a homophone of "pan," a cooking utensil. The punchline, "Pun in, ten dead," plays on these two meanings of the word "pun" to create a humorous and unexpected twist. The use of wordplay in the punchline is what makes the joke funny.

> Susam: I am quite certain that this joke does not rely on the homophone of the word "pan". Do you want to try explaining this joke again?

> ChatGPT: I apologize for misunderstanding the joke. Here is another interpretation:

> This joke is funny because it uses a play on words to create a punchline that is unexpected and humorous. The setup of the joke involves a pun walking into a bar, which sets up the expectation that the punchline will involve a pun or a play on words. However, the punchline takes this expectation and subverts it by stating that ten people died as a result of the pun walking into the bar. This unexpected twist on the setup creates a humorous and absurd resolution to the joke.

I tried a few more prompts here to see if ChatGPT stumbles upon the fact that this is a play on the popular phrase "pun intended" but it could not. It is not surprising considering that a large language model like this does not have a notion of what words sound like. But I was hoping that maybe somewhere in its humongous training data there was a conversation about this joke where someone explained why this joke is funny and ChatGPT may have learnt something from it. But it seemed like ChatGPT was very clueless about this joke.

## Ten Puns

> Susam: Never mind. Let us try another joke.

> ChatGPT: Certainly! Please go ahead and share another joke with me, and I'll do my best to help you understand why it is funny.

> Susam: I once submitted ten puns to a contest hoping one would win, but no pun in ten did.

> ChatGPT: This joke is funny because it uses wordplay, or a play on words, to create a punchline that is unexpected and humorous. In this joke, the word "pun" is used in two different ways: first, as a type of joke that relies on wordplay, and second, as a homophone of "pun," a unit of mass equal to about 1/16 of an ounce. The punchline, "no pun in ten did," plays on these two meanings of the word "pun" to create a humorous and unexpected twist. The use of wordplay in the punchline is what makes the joke funny. Additionally, the joke's setup, in which the speaker submits ten puns to a contest, adds to the humor by implying that the speaker is trying very hard to come up with a successful pun, but ultimately fails.

> Susam: No, that's not it. Although the speaker tries hard and fails, that's not why this joke is funny. There is a clever wordplay on the phrase "no pun intended". Do you see it now?

> ChatGPT: I apologize for misunderstanding the joke. Here is another interpretation:

> This joke is funny because it uses wordplay, or a play on words, to create a punchline that is unexpected and humorous. The punchline of the joke, "no pun in ten did," plays on the phrase "no pun intended," which is often used to indicate that a pun or play on words was unintentional. In this joke, the punchline takes this phrase and subverts it by implying that the speaker intentionally submitted ten puns to a contest, but none of them were successful. This unexpected twist on the phrase "no pun intended" creates a humorous and absurd resolution to the joke.

That was a unhumorous and absurd resolution to my question. Anyway, moving on to the next joke now.

## Infinite Mathematicians

> Susam: I have some technical jokes. Do you want to explain them to me?

> ChatGPT: Sure! I'd be happy to help you understand why technical jokes can be funny. Please go ahead and share the jokes with me, and I'll do my best to explain why they might be considered humorous.

> Susam: An infinite number of mathematicians walk into a bar. The first says, "Give me a beer." The second says, "I'll have half a beer." The third says, "A quarter of a beer, please." The bartender pours two beers and says, "Come on, people. Know your limits."

> ChatGPT: In this joke, the setup involves a group of mathematicians entering a bar and ordering drinks. The punchline, "Come on, people. Know your limits," plays on the double meaning of the word "limits" as both a mathematical concept and a colloquial phrase meaning "restraint." The joke's punchline implies that the mathematicians are unable to properly calculate and order their drinks, which is unexpected and absurd given their expertise in mathematics. This unexpected twist on the setup creates a humorous resolution to the joke.

> Susam: Why does the bartender pour two beers in this joke?

> ChatGPT: In this joke, the bartender pours two beers because the mathematicians are unable to properly calculate and order their drinks. The first mathematician orders a full beer, the second orders half a beer, and the third orders a quarter of a beer. When these orders are added together, they equal two full beers. The joke's punchline, "Come on, people. Know your limits," implies that the mathematicians are struggling to understand the concept of fractions and are unable to properly calculate and order their drinks, which is unexpected and absurd given their expertise in mathematics. The bartender's decision to pour two beers is a humorous resolution to the joke, as it highlights the mathematicians' inability to properly order their drinks.

> Susam: I am pretty sure that the mathematicians are not struggling in this joke. Anyway, can you explain to me why when the orders are added together, they equal two full beers?

> ChatGPT: I apologize for misunderstanding the joke. Here is another interpretation:

> In this joke, the bartender pours two beers because the orders of the mathematicians, when added together, equal two full beers. The first mathematician orders a full beer, which is one full beer. The second mathematician orders half a beer, which is equal to half of one full beer, or 0.5 beers. The third mathematician orders a quarter of a beer, which is equal to one-quarter of one full beer, or 0.25 beers. When these orders are added together, they equal 1 + 0.5 + 0.25, or 1.75 beers. Since it is not possible to pour a fraction of a beer, the bartender pours two full beers to satisfy the orders of the mathematicians. The joke's punchline, "Come on, people. Know your limits," implies that the mathematicians are unable to understand the concept of fractions and are ordering impractical amounts of beer, which is unexpected and absurd given their expertise in mathematics. The bartender's decision to pour two beers is a humorous resolution to the joke, as it highlights the absurdity of the mathematicians' orders.

> Susam: Why did you stop at the third mathematician? There are infinite number of mathematicians. Also, how is 1.75 beers relevant to this joke when the bartender poured 2 full beers?

> ChatGPT: In this joke, the orders for beer from the mathematicians can be added together to find the total amount of beer that they are requesting. The first mathematician orders a full beer, which is one full beer. The second mathematician orders half a beer, which is equal to half of one full beer, or 0.5 beers. The third mathematician orders a quarter of a beer, which is equal to one-quarter of one full beer, or 0.25 beers. If this pattern continued with an infinite number of mathematicians, the orders for beer would add up to the infinite series 1 + 0.5 + 0.25 + 0.125 + 0.0625 + ..., which can be simplified to 2 full beers. This means that the orders of the infinite number of mathematicians, when added together, equal exactly two full beers. The bartender's decision to pour two beers is a humorous resolution to the joke, as it highlights the absurdity of the mathematicians' orders and the unexpected punchline.

Although it required multiple attempts here to have ChatGPT explain this joke there are two things I liked about this conversation: First, right at the beginning ChatGPT mentioned that the joke plays on the double meaning of the word "limits" as both a mathematical concept and a colloquial phrase meaning "restraint". Second, in the end, it did successfully explain that the infinite arithmetic series results in 2.

## Three Logicians

> Susam: Explain another joke to me.

> ChatGPT: Certainly! Please go ahead and share another joke with me, and I'll do my best to help you understand why it might be considered funny.

> Susam: Three logicians walk into a bar. The bartender asks, "Does everyone want beer?" The first logician says, "I don't know." The second logician says, "I don't know." The third logician says, "Yes."

> ChatGPT: This joke is funny because it uses a play on words and a familiar scenario (a group of people entering a bar and ordering drinks) to create a punchline that is unexpected and humorous. In this joke, the setup involves a group of logicians entering a bar and the bartender asking if they want beer. The punchline, "Yes," is delivered by the third logician and subverts the expectations established by the first two logicians, who both say "I don't know" in response to the bartender's question. This unexpected twist on the setup creates a humorous resolution to the joke.

> Susam: Why does the third logician answer answer yes?

> ChatGPT: In this joke, the third logician answers "Yes" because it is an unexpected and humorous resolution to the setup of the joke. The joke is structured as a series of increasingly indecisive responses to the bartender's question of whether everyone wants beer. The first two logicians both say "I don't know," implying that they are unsure or unable to come to a definitive answer about whether they want beer. The third logician's response of "Yes" subverts these expectations by providing a definitive answer that is unexpected and humorous given the indecisive responses of the first two logicians. This punchline effectively resolves the setup of the joke in a way that is unexpected and humorous.

> Susam: It is not just the contrast between the indecisiveness between the first two logicians and the definitive answer of the third logician that is funny here. There is something about logic too involved here. Do you see it?

> ChatGPT: Yes, you are correct. In addition to the contrast between the indecisiveness of the first two logicians and the definitive answer of the third logician, the joke also plays on the idea of logical reasoning and the concept of a logical paradox.

> In this joke, the first two logicians both say "I don't know" in response to the bartender's question of whether everyone wants beer. This creates a paradox, as the logicians are unable to come to a definitive answer about whether they want beer, despite being experts in logical reasoning. The third logician's response of "Yes" resolves this paradox in a humorous way, as it provides a definitive answer that is unexpected given the indecisive responses of the first two logicians. This resolution to the paradox adds to the humor of the joke.

Apparently, this joke was too subtle for ChatGPT to explain convincingly. Moving on to the next joke now.

## Two Hard Things

> Susam: Never mind. Let us do another joke. Alright?

> ChatGPT: Certainly! Please go ahead and share another joke with me, and I'll do my best to help you understand why it might be considered funny.

> Susam: There are only two hard things in Computer Science: cache invalidation, naming things and off-by-one errors.

> ChatGPT: In this joke, the setup involves the speaker stating that there are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors. The punchline is the phrase "and off-by-one errors," which plays on the phrase "two hard things" from the setup. By adding an additional item to the list, the punchline subverts the expectations established in the setup and creates a humorous and unexpected resolution to the joke.

> Additionally, the joke plays on the familiarity of the challenges of cache invalidation and naming things in computer science, and the absurdity of including off-by-one errors as a third challenge adds to the humor of the joke. Off-by-one errors are a common type of programming error that can be relatively easy to fix, so the inclusion of this item in a list of "hard" challenges in computer science is unexpected and humorous.

> Susam: Does including the off-by-one error in the joke itself create an off-by-one error in the joke?

> ChatGPT: No, the inclusion of the phrase "and off-by-one errors" in the joke does not create an off-by-one error in the joke.

> An off-by-one error is a type of programming error that occurs when a programmer uses a loop or array index that is one element too high or too low, leading to an unexpected result or behavior. In the context of this joke, the phrase "and off-by-one errors" is not being used as a loop or array index, and therefore cannot create an off-by-one error in the joke itself. Rather, the phrase is being used as a punchline to the joke, subverting the expectations established in the setup and creating a humorous and unexpected resolution to the joke.

> Susam: But the joke begins by saying that there are two hard things in computer science and it ended up mentioning three hard things instead where the last one was an off-by-one error. Do you still not see an off-by-one error caused by the third hard thing mentioned in the joke?

> ChatGPT: I apologize for misunderstanding the joke. You are correct that the punchline of the joke, "and off-by-one errors," creates an off-by-one error in the joke by adding an additional item to the list of "hard things" in computer science mentioned in the setup. This creates a humorous and unexpected resolution to the joke by subverting the expectations established in the setup.

> The inclusion of the phrase "and off-by-one errors" in the joke creates an off-by-one error in the sense that it implies that there are three hard things in computer science, rather than the two stated in the setup of the joke. This creates a humorous and absurd resolution to the joke, as off-by-one errors are a common but relatively minor challenge in computer science, and their inclusion in a list of "hard things" adds to the absurdity and humor of the joke.

## Octal

> Susam: Alright. I have another joke. Will you explain it to me?

> ChatGPT: Certainly! Please go ahead and share another joke with me, and I'll do my best to help you understand why it might be considered funny.

> Susam: Why don't jokes work in octal? Because 7 10 11.

> ChatGPT: This joke is funny because it uses a play on words and a familiar concept (base numbering systems in computer science) to create a punchline that is unexpected and humorous. In this joke, the setup involves the question "Why don't jokes work in octal?" Octal is a base-8 numbering system used in computer science, so the setup of the joke implies that there is something about octal that prevents jokes from working properly. The punchline, "Because 7 10 11," plays on the idea of base numbering systems by using the numbers 7, 10, and 11 in a way that is unexpected and humorous.

> Susam: What is unexpected about "7 10 11"?

> ChatGPT: In this joke, the punchline "7 10 11" is unexpected because it combines numbers written in different base numbering systems in a way that is humorous and absurd. The numbers 7, 10, and 11 are all written in different bases: 7 is written in base-8 (octal), 10 is written in base-10 (decimal), and 11 is written in base-2 (binary). The joke's punchline combines these numbers in a way that is unexpected and humorous, implying that the use of different base numbering systems is the reason why jokes don't work in octal. This unexpected twist on the setup creates a humorous resolution to the joke.

> Additionally, the punchline "7 10 11" does not have a clear meaning or interpretation, which adds to the absurdity and humor of the joke. The combination of numbers written in different base numbering systems creates a nonsensical and absurd phrase, which is unexpected and humorous given the setup of the joke.

> Susam: Do you know anything about the following joke? "Why was 6 afraid of 7? Because 7, 8, 9!"

> ChatGPT: Yes, this is a well-known joke that uses a play on words and a familiar scenario (one number being afraid of another number) to create a punchline that is unexpected and humorous. In this joke, the setup involves the question "Why was 6 afraid of 7?" The punchline, "Because 7, 8, 9," plays on the idea of counting and the pronunciation of the numbers 7, 8, and 9.

> The punchline "Because 7, 8, 9" subverts the expectations established in the setup by implying that 6 is afraid of the numbers 7, 8, and 9, rather than just the number 7. This creates a humorous and unexpected resolution to the joke, as it implies that 6 is afraid of the act of counting or the progression of numbers. Additionally, the punchline plays on the way that the numbers 7, 8, and 9 are pronounced, as saying "seven, eight, nine" out loud sounds similar to the phrase "scared." This adds to the humor of the joke by creating a play on words.

> Susam: No, "seven, eight, nine" does not sound similar to the phrase "scared" at all.

> ChatGPT: I apologize for misunderstanding the joke. You are correct that the punchline "Because 7, 8, 9" does not create a play on words by sounding similar to the word "scared." However, the punchline is still humorous because it subverts the expectations established in the setup of the joke by implying that 6 is afraid of the numbers 7, 8, and 9, rather than just the number 7. This creates a humorous and unexpected resolution to the joke, as it implies that 6 is afraid of the act of counting or the progression of numbers.

> I apologize for any confusion that my previous response may have caused. Please let me know if you have any further questions or if you would like further clarification on this joke.

## Halloween

> Susam: Here is the last joke I want you to explain today. Ready?

> ChatGPT: Certainly! I'm here to help you understand why a joke might be considered funny. Please go ahead and share the joke with me, and I'll do my best to provide a helpful explanation.

> Susam: Why do programmers always mix up Halloween and Christmas? Because Oct 31 = Dec 25.

> ChatGPT: This joke is funny because it uses a play on words and a familiar concept (calendar dates) to create a punchline that is unexpected and humorous. In this joke, the setup involves the question "Why do programmers always mix up Halloween and Christmas?" The punchline, "Because Oct 31 = Dec 25," plays on the idea of calendar dates and the abbreviations for the months of October and December.

> The punchline "Because Oct 31 = Dec 25" subverts the expectations established in the setup by implying that the dates of Halloween (October 31st) and Christmas (December 25th) are equivalent, rather than being two separate holidays. This creates a humorous and unexpected resolution to the joke, as it implies that programmers are unable to distinguish between the two holidays. Additionally, the punchline plays on the abbreviations for the months of October and December, as "Oct" and "Dec" are often used as abbreviations for these months. This adds to the humor of the joke by creating a play on words.

> Susam: No, that's not it. The joke has something to do with numeral systems and radix. Do you see what is funny about it now?

> ChatGPT: I apologize for misunderstanding the joke. You are correct that the punchline "Because Oct 31 = Dec 25" is also humorous because it plays on the idea of numeral systems and the concept of a radix.

> In the context of this joke, the punchline "Oct 31 = Dec 25" implies that the dates of Halloween (October 31st) and Christmas (December 25th) are equivalent when expressed in a different numeral system or radix. This creates a humorous and unexpected resolution to the joke, as it implies that programmers are unable to distinguish between the two holidays because they are confusing the dates when expressed in a different numeral system.

> I apologize for any confusion that my previous response may have caused. Please let me know if you have any further questions or if you would like further clarification on this joke.

> Susam: How exactly does Oct 31 and Dec 25 become equivalent when expressed in different numeral systems or radix? Can you elaborate please?

> ChatGPT: In the context of this joke, the punchline "Oct 31 = Dec 25" implies that the dates of Halloween (October 31st) and Christmas (December 25th) are equivalent when expressed in a different numeral system or radix. This means that the two dates can be represented using the same numerical value in a different numeral system.

> For example, if the date of Halloween (October 31st) is expressed in base-8 (octal) notation, it would be written as "137." Similarly, if the date of Christmas (December 25th) is expressed in base-8 (octal) notation, it would also be written as "137." In this case, the two dates would be equivalent when expressed in base-8 notation, as they both have the same numerical value of 137.

> This joke plays on the idea of numeral systems and the concept of a radix to create a punchline that is unexpected and humorous. By implying that the dates of Halloween and Christmas are equivalent when expressed in a different numeral system, the joke creates a humorous and absurd resolution to the setup of the joke.

> Susam: Sorry, but that is incorrect. Decimal 31 = Octal 37, not 137.

> ChatGPT: I apologize for the error in my previous explanation. You are correct that the octal representation of the number 31 is "37," and that this is equivalent to the decimal value 37, not 137.

> Susam: When we take the decimal number 25 and convert it to octal, we get 31. Do you see why the joke is funny now?

> ChatGPT: The punchline "Oct 31 = Dec 25" is humorous because it plays on the idea of numeral systems and the concept of a radix.

> For example, if the date of Christmas (December 25th) is expressed in base-8 (octal) notation, it would be written as "31." Similarly, if the date of Halloween (October 31st) is expressed in base-10 (decimal) notation, it would also be written as "25." In this case, the two dates would be equivalent when expressed in these different numeral systems, as they both have the same numerical value of 25.

> This joke plays on the idea of numeral systems and the concept of a radix to create a punchline that is unexpected and humorous. By implying that the dates of Halloween and Christmas are equivalent when expressed in a different numeral system, the joke creates a humorous and absurd resolution to the setup of the joke.

> I hope this helps to clarify the humor of this joke. Please let me know if you have any further questions or if you would like further clarification on this concept.

> Susam: I have no further questions. It was nice talking to you. Bye and have a nice day!

> ChatGPT: You're welcome! I'm glad that I could help you understand the joke. If you have any other questions in the future, don't hesitate to reach out to me. I'll be here to help.

> I hope you have a great day as well! Bye for now.
