Here is the joke. When I tell you this story in person, of course, it’ll take forty minutes at least.
A tuna struggles its entire life for revenge, finally finding its way into the famous sushi bar. When the fish finally sees the famous sushi chef, it cries out: “You killed my father!”
The chef says, “That’s my business, fish.”
The tuna thinks for a moment (amazed that a human can speak English) and says “Very well. Then I challenge you to a game of Go. If I win, you must stop being a chef forever. And maybe work at an Aquarium.”
“And if I win?” asks the chef, assembling the board for their game.
The fish replies, “Then I will die honorably as food for your customers.”
So they sit and begin to play. This tuna has played Go all its life, and in a few turns the tuna has the chef beaten.
“Looks like I win,” says the fish. The chef nods and plunges his knife into the tuna’s belly.
“But I won!” says the tuna.
“So did you father,” says the chef.
Appendix: The game “Go” is kind of like chess. When I first heard the joke, the person telling it used chess, but it really should be Go instead, and I think that all jokes should have a small appendix, like this.
