World's Funniest joke

Was listening to my usual morning radio show on my drive to school this morning.  Apparently the world's funniest joke according to British scientists is some version of the following:

Joe and Dave are hunting when Dave keels over. Frantic, Joe dials 911 on his cell phone and blurts, "My friend just dropped dead! What should I do?"
A soothing voice at the other end says, "Don't worry, I can help. First, let's make sure he's really dead."
After a brief silence, the operator hears a shot. Then Joe comes back to the phone. "Okay," he says nervously to the operator. "What do I do next?"
