World's funniest joke?

Something for Friday. ABC Online reports that the world's funniest 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 man pulls out his phone and calls emergency services. He gasps to the operator: 'My friend is dead! What can I do?' "The operator, in a calm, soothing voice, replies: 'Take it easy. 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 hunter says: 'okay, now what?'"
I don't believe it. Sounds like fun research though. The full findings are supposedly available at www.laughlab.co.uk, although I only get a connection refused.
