World's Funniest Joke?

CNN is reporting that after months of searching, a group of researchers have found the world’s funniest joke. Here it 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 takes 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 gunshot is heard. Back on the phone, the guy says: “OK, now what?”

I don’t think it was that funny, so here are my votes for the funniest jokes in the world:

What do gang bangers wash their whites with?

Why do women wear makeup and perfume?
Because they’re ugly and they smell bad.
