A guy sticks his head into a barber shop and asks "Hey, Buddy! how long before I can get a haircut?"
The barber look around the shop and says "about 2 hours," and the guy leaves.
A few days later the same guy sticks his head in the door and asks..."how long before I can get a haircut?"
Again, the barber looks around at shop full of customers and says"about 2 hours." The guy leaves.
A week later the same guy sticks his head in the shop and asks"how long before I can get a haircut?" The barber looks around the shop and says "about an hour and a half". The guy leaves.
The barber looks over at a friend in the shop and says "Hey, Joey, I'll give you a free cut if you follow that guy and see where he goes."
In a little while, Joey comes back into the shop laughing hysterically. The barber says,"this must be good, where did he go when he left here?"
Joey says, "To your house!"
