One day, a priest went into a public bathroom to use the cubical. While he was on the toilet, he heard moaning coming from the stall next to him. He stood up to look over, and there was a young man, sitting on the toilet playing with himself.
The priest was shocked. He told the young man that he knew what he was doing in there and that he should save it for marriage.
The young man agreed to this only because it was coming from a priest.
About a week later, the priest ran into the young man at the mall and asked him how he was doing with his problem.
The young man replied, "Great father! I've saved a whole quart!"
