You may have heard this one but its still a good one
 

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?"

(sings Barenaked Ladies)

Woo-hoo-hoo, it's all been done... woo-hoo-hoo, it's all been done... woo-hoo-hoo, it's all been done (done, done) before...

Now look what you made me do. I don't think the search function is working right now, so I guess I'll let it slide this time. :)

It's the funniest joke in the world!

(really)

I'v heard it but usually it's just two hunters. Making them New Jersey hunters makes the joke better, and funnier. Like the old "Ya hear they don't like Jehovah's witnesses in New Jersey?" "Man, they don't like ANY witnesses in New Jersey!"

Yeah I've heard it but man, it's still a classic :)
