A 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 the shop full of customers and says, "About 3
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.
He keeps asking how long he has to wait for a haircut, but then doesn't come
back."
A little while later, Bill comes back into the shop, laughing hysterically.
The barber asks, "Bill, where did he go when he left here?"
Bill replies, "Your house!"
