One day a mother was cleaning her teenage son's room, and in his closet she found an S&M magazine. Unsure of how to confront her son, she hid the magazine until her husband came home. She showed her husband what she'd found, he looked at the magazine and then handed it back to her without a word.
She finally asked him, "Well, what should we do about this?"
He looked back at her hesitantly and said, "Well, I don't think you should spank him."
