A guy stuck his head into a barber shop 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 only."
The guy left. The barber turned to a friend and said: "Hey, Bill, do me a favour. 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: "To your wife!"
