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 him 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, wiped the tears from his eyes and said, 'Your
house!'

Good one!
