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 and 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 laughing hysterically.
The barber asks, "Bill, where did he go when he left here?"
Bill looked up and said, "To your house."
