Funniest Joke in the World

One of Monty Python's most popular sketches, this one envisions a future where comedy is used as a weapon of warfare after a "Killer Joke" that causes people to laugh themselves to death is unveiled, resulting in casualties around the globe. In reality, the only version of the joke given in the sketch is quasi-German gibberish, but if put into Google Translate, it yields the interesting result "FATAL ERROR", indicating even those at Google have recognized the impact of the sketch.

Jim Carrey, who has called the Python troupe "the Justice League of comedy", mentioned on the TV show Monty Python's Best Bits (mostly) that this sketch contained one of his favorite Python moments - the scene in which joke-writer Ernest Scribbler dies from laughing.
