The Afterlife

Two friends make a pact that if either of them dies, the other will visit a medium and try to make contact to find out what heaven is like. By and by Bill drops dead of a heart attack, so John goes to the medium.

John: "Bill, Bill, are you there? How are things?"

Bill (through the medium): "John! Yes, I'm here. Things are wonderful! The grass is green, the sky is blue with lovely puffy clouds, and the cows! Oh, John, you would not believe the cows!"

John: "Wait, there are COWS in heaven?"

Bill: "What heaven? I'm a bull on the pampas in Argentina!"
