Little Johnny's preschool class went on a field trip to the fire station. The fireman giving the presentation held up a smoke detector and asked: "Does anyone know what this is?"
Little Johnny's hand shot up and he said: "That's how Mommy knows supper is ready!"
One day Little Johnny's mother was cleaning his room when she found a Bondage and S&M magazine under his bed. This was very upsetting to her. So she waited until Little Johnny's dad came home, handed him the magazine and told him: "Look what I found under Johnny's bed. What do you think we should do about it?"
Dad looked took the magazine, thumbed through a few pages, then handed it back to her saying: "Well... I don't think we should spank him."
