A man was walking one day, when he came to this big house in a nice neighborhood. Suddenly he realized there was a couple making love out on the lawn. Then he noticed another couple over behind a tree. Then another couple behind some bushes by the house.

He walked up to the door of the house, and knocked. A well dressed woman answered the door, and the man asked what kind of a place this was.

"This is a brothel," replied the madam.

"Well, what's all this out on the lawn?" queried the man.

"Oh, we're having a yard sale today!"
