An elderly man walks into the barbershop for shave and a haircut, but he tells the barber he can't get all his whiskers off because his cheeks are so wrinkled from age.
The barber says "not to worry" ... and gets a little wooden ball from a cup on the shelf and tells him to put it inside his cheek to spread out the skin.
When he's finished, the old man tells the barber that was the cleanest shave he's had in years. But he wanted to know what would have happened if he had swallowed that little ball.
The barber shrugged and said, "Just bring it back in a couple of days like everyone else does."
