One morning a man came into the church on crutches.  He stopped in front of the holy water, put some on both legs, and then threw away his crutches.  An altar boy witnessed the scene and ran into the rectory to tell the priest what he'd just seen.

Son, you've just witnessed a miracle, the priest said.  Tell me where this man is now?

Flat on his ass over by the holy water, the boy informed him.
