A little boy was sitting on the footpath with a bottle of Turpentine. He was shaking it up and watching all the bubbles.
A priest came along and asked the little boy what he had.
The little boy said, "This is the most powerful liquid in the world; it's called Turpentine."
The priest said, "No, the most powerful liquid in the world is Holy Water. If you rub it on a pregnant woman's belly, she'll pass a healthy baby."
The little boy replied, "If you rub turpentine on a cat's ass, he'll pass a Harley Davidson!"
