A nun was in a hurry on her way to her job at the local Catholic hospital when her car suddenly ran out of petrol. Luckily, she was around the corner from a petrol station, so she got out of her car and quickly walked there.
At the station, she asked the attendant to give her a few litres of petrol so that she could start her car and drive it over to fill it up. The attendant told her that he only had one can, and he had just loaned it to someone else.
She told the attendant that she was in a hurry and would look in her car to find something to hold it. When she got back the the car, the only suitable container she found was a bedpan, which looked like it could easily hold the petrol.
She brought the bedpan to the station and the attendant filled it with petrol. The nun got back to her car and started to pour the petrol 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!”
