Way back when the world was in black and white, the comedian George Burns used to have lunch with several friends every week. One of those friends was Groucho Marx
George Burns was a fan of seafood, and his standard order was the sea bass. There was a hit song a back then called “You’ve Got to See Mama Every Night or You Can’t See Mama at All.” One day when Burns ordered the sea bass, Groucho said, “You know, you’ve got to see bass every night or you can’t see bass at all.” This is a good example of a Groucho Marx joke, but not an example of a good Groucho Marx joke.
Anyway, for a long, long time after that, every week Burns would order the sea bass and Groucho would say “You know, you’ve got to see bass every night or you can’t see bass at all.” Groucho enjoyed it more every time he said it. George Burns not so much.
Finally, Burns had had enough. Before everybody had sat down he pulled the waiter aside and said, “Look, I don’t want to order at the table. Please just make a note that I’ll be having the sea bass.”
The waiter said, “Yes sir. By the way, did you know that you’ve got to see bass every night or you can’t see bass at all?”
