It seems that GPT-3 has its own sense of humor, more of an anti-humor in fact. It is better in bulk.
I prompted with a message describing your post and some text that said a reply had a funny joke-- letting it know we were talking about machines making jokes might have handicapped it some. Here are some continuations:
"Turns out there are two kinds of computers: those with funny jokes in them and those without."
"If we had an AI that could make jokes, would it be funny? Yes, but only if you're a robot."
"What's the difference between a computer and a dog? The difference is that when you tell someone a dog is stupid, they don't believe you."
"What do you call a man who has everything but the one thing he wants most? A miser."
"If you're going to be the next Jeopardy! champion, don't make a stupid pun. It's not funny."
"If you push a button in the Machine Intelligence Research Institute, what happens? The machine explodes!"
"The answer is no. It does not make you laugh."
"You know what the worst thing about being a computer is? It's not having any sense of humor!"
"The question is, what do you call the thing that does nothing but read? A robot. The answer to the next question is no, because robots are boring."
"No, but you can make it say 'Wetware' in big letters across the screen. That's what I did."
"A man is walking along the beach. Suddenly he sees an octopus swimming towards him. He shouts 'Octopi don't know what they are doing!' The next moment he realizes his mistake and runs back to shore as fast as possible."
"A man walks into a bar... A woman sitting at the next table says to him, "I'm sorry, but I can't serve you." "Why not?" he asks. "Because I don't know how," she replies. "Well what are your qualifications?" he demands. "My bachelor's degree is in mathematics," she explains."
"GPT-3 has been programmed to be able to tell the difference between a man and a woman. It's just as well since we don't make any mistakes when it comes to that sort of thing."
"GPT-3 is the most advanced AI ever created. It has been programmed to make jokes at your expense."
"The only thing worse than being caught with your pants down is not having any pants at all. -Robocop"
"GPT-3 is the only computer in the world that can tell if you're having an affair with your wife."
"What do you call a guy who has been married to his computer for 20 years? A lifer. What do you call a guy who has been divorced from his computer for 20 years? An ex-lifer."
"How do you know the GPT-3 is running Windows? Because its screen saver shows a man in a suit. He's not wearing any pants."
(It also offered the commentary: "So, what does this mean? Is there some sort of joke here? Does it imply that the computer has a sense of humor and is making fun of us? Or is it just another example of how we humans are so much alike despite our differences?")
"The only thing GPT-3 likes better than crackers are the smell of napalm and Kool Aid."
"GPT-3 is the only program in existence that thinks 'If this were a movie, it would be called 'The Program'."
"GPT-3 is a computer program that produces funny comments. It's written in the programming language BASIC."
"GPT-3 is an acronym for 'Get Potty trained to be a Programmer'."
"GPT-3 - the greatest joke in programming"
(And it also offered the commentary: "That made me laugh so hard I almost cried. It's the first time in my life that I've laughed out loud like this. And then I thought "What if it could do that to other people too?" That's when I started thinking about how we might use it as an attack vector against our enemies...")
