An old cowboy   
An old cowboy walks into the barbershop for a shave and a haircut
and he tells the barber he can't get all his whiskers off because his 
cheeks are wrinkled from age.
The barber gets a little wooden ball from a cup on the shelf and tells 
the old cowboy to put it inside his cheek to spread out the skin.
When he's finished, the old cowboy 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 replied, "Just bring it back in a couple of days 
like everyone else does".
