One day a guy sticks his head into a barbershop and asks, “How long before I can get a haircut?”

The barber looks around the shop and says, “About two hours.”

The guy leaves.

A few days later the same guy sticks his head in the door and asks, “How long before I can get a haircut?”

The barber looks around at his shop full of customers and says, “About two hours.”

The guy leaves.

A week later the same guy sticks his head in the shop and asks, “How long before I can get a haircut?”

The barber looks around the shop and says, “About an hour and a half.”

The guy leaves.

The barber looks over at a friend in the shop and says, “Hey, Ben, follow that guy and see where he goes.”

In a little while, Ben comes back into the shop laughing hysterically.

The barber asks, “Ben, where did that guy go when he left here?”

Ben looks at him and says, “To your house.”
