Reminds me of an old joke. A guy gets a flat in front of an insane asylum (excuse the politically incorrect term - OLD joke). He takes off the lug nuts and puts them in the hub cap, but leaves them a little too close to the road. A car comes wide around a corner and hits his hub cap scattering his lug nuts everywhere. He searches and searches, but can't find them. He sits down and says "what the heck am I going to do now?" Then he hears a voice from inside the fence of the asylum, "just take one lug nut off each of the other three wheels and use them to bolt the spare on." The guy says, "that's amazing!" "I never would have thought of that!" "How did YOU come up with such an idea?" The asylum resident says, "I'm in here because I'm crazy, not stupid!"
