A group of nuns were traveling in a car when it had a flat tire.

They
got out and tried to change it, but being rather unworldly, they
don't really know how.

Luckily, a truck came along and the driver
offered to change it for them.

They gratefully accepted.

As the
trucker jacked up the car, it slipped from the jack and he yelled,"Son-of-a-bitch!"

The eldest nun said to him, "That is not nice
language. We understand that you are upset, but you mustn't use such
language."

"Sorry, Sister," he said, and tried again.

Again it slipped, this
time almost smashing his fingers.

"Son-of- a-bitch," he yelled again.

"Please, don't use such language. If changing our tire is causing you
to do so, it would be better if you didn't help us."

"But I get so
upset, and it just comes out."

"Well," said the nun, "say something
else when you get upset, something like 'Sweet Jesus, help me.'"

So the trucker tried to jack up the car again.

And again it slipped.

He started to say "Son.." but he corrected himself and said, "Sweet
Jesus, help me."

At that, the car miraculously rose into the air all
by itself.

The nuns looked at the car in wonder, exclaiming, "Son-of-a-bitch!"
