A guy sticks his head in a barbershop and asks, "How long before i can get a haircut?"
The barber replies, "About two hours," and the guy leaves.
A week later the guy pops in and asks the same question.
"Two hours," replies the barber. Again the guy leaves.
The barber has his friend follow him. Ten minutes later the friend returns.
"Where did he go?" demands the barber.
"To your house."
