One morning a man comes into church on crutches. He stops In front of  the Holy water and splashes some of it on both of his legs, then throws away his crutches.
 
An altar boy witnessed the episode and runs into the rectory to tell the
priest what he'd just seen.
 
Without batting an eye, the priest says, 'Son, you've just witnessed a
miracle. Tell me, where is this man?
 
'Flat on his arse, Father, over by the holy water.'
