Turpentine v Holy Water

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 a*se, he'll pass a
Harley Davidson !'
