Cork
Two guys are in a locker room when one guy notices the other guy has a cork in his ass.

He says, "How'd you get a cork in your ass?"

The other guy says, "I was walking along the beach and I tripped over a lamp. There was a puff of smoke, and then a red man in a turban came oozing out. He said, "I am Tonto, Indian Genie. I can grant-um you one wish."

And I said, "No shit!"
