A nun was in a hurry on her way to her job at the local Catholic Charity Hospital when her car suddenly runs out of gas. Luckily, she was only a block and a half from a gas station, so she got out of her car and quickly walked there.
At the station, she asked the attendent to give her a quart of gasoline so that she could start her car and drive it over to fill it up. The attendent told her that he only had one gas can, and he just loaned it to someone else.
She told the attendent that she was in a hurry and would look in her car to find something to hold the gas. When she got back the the car, the only suitable container she found was a bedpan, which looked like it could easily hold a quart of gas.
She brought the bedpan to the station and the attendent filled it with gas. The nun got back to her car and started to pour the gas from the bedpan into her car.
Just as she started pouring, two men walked by. One of the men said to the other "If that car starts, I'm converting to catholicism forever!"
