How's this one? Its called "The Haircut"?

A guy stuck his head into a barbershop and asked, "How long before I

can get a haircut?" The barber looked around the shop full of customers

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 at the shop and said, About 3 hours. The guy

left.

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 half. The guy left. The barber turned to a

friend and said, "Hey, Bill, do me a favor. Follow that guy and see

where he

goes. He keeps asking how long he has to wait for a haircut, but then

he doesn't ever come back." A little while later, Bill returned to the

shop,

>laughing hysterically. The barber asked, "So where does that guy go

when he leaves?" Bill looked up, tears in his eyes and said, "Your

house."
