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, "A couple of 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, "I'm pretty busy 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 a half today."

The guy left. The barber turned to his assistant and said... "Hey, Bob, do me a favor.  Follow that guy who just put his head around the door 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, Bob returned to the shop, laughing hysterically. The barber asked, "So, where does that guy go?"

Bob looked up, wiped the tears from his eyes and said... "Your house!"
