A man died and he went to heaven. In heaven there were very huge walls with millions of clocks attached on it. Sometimes a hand on a clock was moving a little bit.
The man called Saint Peter: “Mr. Peter, may I ask you a question… What are all these clocks doing here?”
Saint Peter: “Every time when a woman on earth wants to have sex, the hand of her clock is moving a second.”
Man: “So every woman has her own clock. But how are they organized?”
Saint Peter: “Over here we’ve got the Brunette-wall. Over there the black haired women-wall. And over there the blond-wall.”
Man: “And what about a redhead-wall?”
Saint Peter: “Oh we use their clocks in the kitchen as a ventilator.”
