Forgetful Priest
The local parish priest is furious. Somebody has stolen his bicycle. He tells his housekeeper, "I have a suspicion young Johnny may have taken my bike but I don't have proof."
The housekeeper replies, "Why don't you do a sermon on the ten commandments next Sunday. When you get to 'thou shalt not steal' look directly at young Johnny and watch for his reaction.
The priest thinks it is a good idea and the next Sunday he gives a thunderous sermon about the ten commandments.
When he returns to the rectory his housekeeper asks, "Well, how did it go?"
The priest looks at her shamefaced and replies, "It was most embarrassing. When I got to 'thou shalt not commit adultery' I suddenly remembered where I'd left my bike"
