Deadliest joke of man kind!

I can't say this joke because if I knew it I would probably be dead and If I didn't die maybe some of you would. I don't remember the story very well but i'll try my best. There was a comedian that wrote the greatest joke of mankind. He read to himself and soon died of laughter. His wife came in shocked by what happened and saw the paper on his desk. She read it and died as well. The butler came inside the room and saw the paper.You guys probably know what happened.

Please note that this may or may not be a fact, I just heard it a long time ago.

here it is. it was originally from monty python

God damnit i wish could speak german so i could understand the joke
