Diesel Bombers - A group of nuns

A group of nuns were traveling in a car when it had a flat tire.
They
got out and attempted to change it, but being rather unworldly, they
had
no idea how to go about it. Fortunately, 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.
"Son-of-a-bitch!" he screamed.

"Sir, that is inappropriate language," the eldest nun said.
"We understand you're upset, but must you use such
language?"

"My apologies, Sister," he replied, and tried again. It
slipped again and nearly smashed his fingers.
"Son-of-a-bitch!" he screamed.

"Please, sir, we would ask you again to not use such
language," the nun scolded. "If changing our tire is causing you to
do
so, perhaps it would be best if you didn't help us."

"I'm sorry, Sister, but I get so upset that it just comes
out," the trucker replied.

"Well," said the nun, "say something else when you get
upset. Say something like 'Dear Lord, help me'."

Once more, the trucker attempted to jack up the car and
again it slipped. He began to blurt out "Son..." but
quickly caught himself and said, "Dear Lord, help me."

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

Staring in amazement, the nuns exclaimed, "Son-of-a-bitch!"
