Funny Question

Professor Wiseman, of the University of Hertfordshire has declared that he has scientifically proven that this is the world's funniest joke:

A couple of New Jersey hunters are out in the woods when one of them falls to the ground. He doesn't seem to be breathing, his eyes are rolled back in his head. The other guy whips out his cell phone and calls the emergency services. He gasps to the operator: "My friend is dead! What can I do?" The operator, in a calm soothing voice says: "Just take it easy. I can help. First, let's make sure he's dead." There is a silence, then a shot is heard. The guy's voice comes back on the line. He says: "OK, now what?"

Personally, I prefer the one about the nun, the cormorant, and the cement mixer.

Update: For those who are interested, here is the world's second funniest joke:

Sherlock Holmes and Dr Watson go on a camping trip. After a good dinner and a bottle of wine, they retire for the night, and go to sleep.
Some hours later, Holmes wakes up and nudges his faithful friend. "Watson, look up at the sky and tell me what you see."
"I see millions and millions of stars, Holmes" replies Watson.
"And what do you deduce from that?"
Watson ponders for a minute.
"Well, astronomically, it tells me that there are millions of galaxies and potentially billions of planets. Astrologically, I observe that Saturn is in Leo. Horologically, I deduce that the time is approximately a quarter past three. Meteorologically, I suspect that we will have a beautiful day tomorrow. Theologically, I can see that God is all powerful, and that we are a small and insignificant part of the universe. What does it tell you, Holmes?"
Holmes is silent for a moment. "Watson, you idiot!" he says. "Someone has stolen our tent!"
