The Barber Shop

   This guy sticks his head into a barber shop and asks, "How long before
   I can get a haircut?" The barber looks around the shop and says,
   "About 2 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 shop
   full of customers and says, "About 2 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, 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."
