So this guy sticks his head into a barbershop and asks “how long before I can get a haircut?”

The barber looked around the shop full of customers and says “about two 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 the shop and said “about three 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.”  The guy left.

The barber turned to his friend and said “hey, Bob, 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 he never comes back.”

A little while later, Bob returned to the shop laughing hysterically.   The barber asked “so, where does he go when he leaves?”

Bob looked up and wiped tears from his eyes and said . . . .

“Your house!”
