How long for a haircut?

[Bob259]

A barber kisses his wife goodbye and heads into work. Later that morning,
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 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 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 when he leaves?"
Bob looked up and said, "Your house!"
