A group on nuns were traveling in a car when it got a flat tire. They got out and tried to change it, but being rather unworldly did not know how to do it.
Luckily, a truck came along and the male driver offered to change it for them. They gladly accepted. As the trucker jacked up the car, it slipped from the jack. “Son of a bitch,” he yelled.
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 mashing 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 ike ‘Sweet Jesus, help me'”.
So the trucker tried to jack up the car again. Again it slipped.
He started to say “So..”, but he corrected himself and said, “Sweet Jesus help me.” At that, the car just lifted up into the air by itself.
The nuns looked at the car floating a foot above the ground and in unison exclaimed, “Son of a bitch!”
