The world's funniest joke is a term used by Richard Wiseman of the University of Hertfordshire in 2002 to summarize one of the results of his research. For his experiment, he created a website where people could submit and rate over 10,000 jokes. Purposes of the research included discovering the joke that had the widest appeal and understanding among different cultures, demographics and countries.
The winner:
Two hunters are out in the woods when one of them collapses. He doesn't seem to be breathing and his eyes are glazed. The other guy whips out his phone and calls the emergency services. He gasps: "My friend is dead! What can I do?" The operator says: "Calm down, I can help. First, let's make sure he's dead." There is a silence, then a shot is heard. Back on the phone, the guy says: "OK, now what?"
An early runner-up was this joke:
"Sherlock Holmes and Dr. Watson are going camping. They pitch their tent under the stars and go to sleep. Sometime in the middle of the night Holmes wakes Watson up.
"Watson, look up at the stars, and tell me what you deduce."
Watson says, "I see millions of stars and even if a few of those have planets, it's quite likely there are some planets like Earth, and if there are a few planets like Earth out there, there might also be life."
Holmes replied: "Watson, you idiot, somebody stole our tent!"
Personally guys I think we've heard better but they're not bad
