A shady-looking guy sticks his head into a barbershop and asks, “How long before I can get a haircut?”
The barber looks around the shop and says, “About two hours.” The guy smiles and leaves.
The barber is curious about this, looks over 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.
“Bill, where did he go when he left here?”
“To your house.”
