An old Indian went into the drugstore "Me Wantum Rubber!"
The proprietor gives him one, and he leaves. Next day, he's back.
" No good. Left ball go WUMP, right ball go WUMP, rubber go BANG!"
So the proprietor gives him the deluxe, superstrong, guaranteed condom. The next day, he's back.
" No good. Left ball go WUMP, right ball go WUMP, rubber go BANG!"
So the proprietor goes into the back, takes an inner tube from a truck tire, welds up a condom from it, and give it to him. The next day, he's back, but he's in rough shape.
" No good. Left ball go WUMP, right ball go WUMP, rubber go WUMP, balls go BANG!"
