In the "Casa Bonita" episode of South Park, Jimmy tells the setup of a knock-knock joke: -Knock-knock! -Who's there? -Ingmar Bergman! -Ingmar Bergman, who? Before he can tell us the punchline, he is literally punched-out by Cartman. So my question is, does anyone know of an existing punchline to this joke? My hunch is that the South Park guys just made this one up. And if that's the case, can anyone think of a great punchline for this setup?
