How Long Before I Can Get A Haircut?

A guy sticks his head in the barber shop 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 get a haircut?"

The barber looks around the 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 an says, "About an hour and half." The guy leaves.

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

In a little while, Bill comes back into the shop, with his head down, looking embarrassed.

The barber asks, "Bill, where did he go when he left here?"

Bill looks up and says, "To your house."
