Out of Gas

Two nuns were driving alone out in the boonies. They ran out of gas. Fortunately they could walk to a gas station not far away, where they asked to purchase a can of gasoline.
"I'm sorry, sister," said the attendant, "but all I have for you to carry it in is an old chamberpot." The nuns agreed that this would be fine. They returned to the car.
As they were pouring the gasoline into the tank, a man drove by, stopped his car, and said, "Oh sister, if only I had your faith."

Two Nuns

There were two nuns: one known as Sister Mathematical (SM), and the other known as Sister Logical (SL). It was getting dark, and they were still far away from the convent.
SM: Have you noticed that a man has been following us for the past thirty-eight and a half minutes? I wonder what he wants.
SL: It's logical. He wants to rape us.
SM: Oh, no! At this rate he will reach us in 15 minutes at the most? What can we do?
SL: The only logical thing to do of course is to walk faster.
SM: It's not working.
SL: Of course it's not working. The man did the only logical thing. He started to walk faster, too.
SM: So, what shall we do? At this rate he will reach us in one minute.
SL: The only logical thing we can do is split. You go that way and I'll go this way. He cannot follow us both.
So the man decided to follow Sister Logical. Sister Mathematical arrived at the convent and was worried about what happened to Sister Logical. Then, Sister Logical arrived.
SM: Sister Logical! Thank God you are here! Tell me what happened!
SL: The only logical thing happened. The man couldn't follow us both, so he followed me.
SM: Yes, yes! But what happened then?
SL: The only logical thing happened. I started to run as fast as I could and he started to run as fast as he could.
SM: And?
SL: The only logical thing happened. He reached me.
SM: Oh, dear! What did you do?
SL: The only logical thing to do. I lifted my dress up.
SM: Oh, Sister! What did the man do?
SL: The only logical thing to do. He pulled down his pants.
SM: Oh, no! What happened then?
SL: Isn't it logical, Sister? A nun with her dress up can run faster than man with his pants down.
...And for those of you who thought it would be dirty, say two Hail Marys!
