A motorist had a flat tire in front of an insane asylum. He took the wheel off, and the bolts that held the wheel on rolled into the sewer. A patient, looking through the fence, suggested that he take one bolt off of the remaining three tires to hold up the new tire until he got to a service station. The motorist thanked him profusely and said, “I don’t know why you are in that place.” The patient said, “I’m here for being crazy, not stupid.”
