One of my students told me that this ineident actually happened. He went on to elaborate that the flat tire occurred alongside a large mental institution near our college. While the hapless motorist sat pondering his problem, he attracted the attention of several "residents" of the institution, who gathered near the motorist along the chain link fence that separated them. One resident offered this solution to the motorist's problem: Remove one lug nut from each of the other three tires and use them to attach the spare. Each tire should hold securely with three lug nuts until the motorist reaches a gas station. The grateful motorist thanked the institution resident and then asked, "How'd you think of such a good solution to this problem?" The resident replied, "I'm not dumb, I'm just crazy!"
