Three scientists are doing an experiment. They are trying to find out what happens when you stick a cork in an elephant's ass.
In the lab, they each look at each other and decide that they should hire a monkey to do it. The monkey sticks the cork up the elephant's ass, and the scientists wait three weeks.
The monkey pulls out the cork, and all three scientists go back and discuss what they saw.
The first one, standing one mile away, says all he could see was a wave of brown, then it all went black. The second, standing two miles away, said the same. The third, who was standing three miles away, said all he could see was the other two get consumed by a massive cloud of brown.
