Richard Wiseman from the University of Hertfordshire put together a study to find the world's funniest joke. He set up a website called Laugh Lab in 2001. After getting the ratings of 1.5 million people, he concluded that he had found the world's funniest joke.

The joke is: 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?"

Buzzfeed decided to put the joke to the test and see if people would actually laugh at it. Watch the video to see if it passes the test.
