A guy sticks his head in the barber shop and asks, "How before I can get a haircut?"

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

The guy walks out. 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 the shop full of customers and says, "About two hours."

Once again, the guy leaves the shop.

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."

Again, the guy walks out. The barber is getting curious.

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

A little while later, Bill comes back into the shop laughing. The barber asks, "Bill, where did the guy go when he left here?"

"To your house."
