this one is rather crude or gross. I'll try to keep it clean.
used to work in a machine shop. this one old fart had a physical problem with his "boys" elephantitus or something like that. well he could with his pants still pulled up and buttoned take his boys out over his waistband and let them hang out
he would then walk up to an unsuspecting sole and lift his shirt up to expose his "boys" hanging over his waistband.
you should have seen the looks of people when they would look down and see those grapefruits hanging there. :--)
