A guy stuck his head into a barbershop and asked, "How long before I can get a haircut?" The barber looked around the shop and said, "About 2 hours." The guy left.

A few days later the same guy stuck his head in the door and asked, "How long before I can get a haircut?" The barber looked around his shop, full of customers, and said, "About 2 hours." The guy left again.

A week later, the same guy stuck his head in the shop and asked, "How long before I can get a haircut?" The barber looked around the shop and said, "About an hour and a half." The guy left again. The barber looked over at a friend in the shop and said "Hey, Bill, follow that guy and see where he goes."

After a while, Bill came back into the shop laughing hysterically. The barber asked, "Bill, where did he go when he left here?"

Bill looked up from his laughter and said, "Your house!"
