I heard this story in Palm Springs
There was a salesman who was driving on his way home. As often happens with motorists, he had a flat tire and he pulled over on the side of the road to change it. There was a decorative wooden fence that went around several acres of land where he had pulled over. And on top of the ridge in the distance was a mental institution. The salesman got out of his car only to find he was in waist high weeds. He removed the jack and spare tire. He loosened the five lug nuts on the flat tire and then jacked the car up so that he could remove it. As he was doing so, he noticed one of the patients from the mental hospital, who had wandered down to his location, was leaning against the wooden fence observing his tire-changing efforts
The salesman removed each lug nut and placed them in his wheel cover so as not to lose them in the tall grass. His back was aching from having been stooped over for so long so he decided to stand up to stretch the muscles in his back. As he did so, the heel of his shoe caught the wheel cover causing it to flip up and throwing all of the lug nuts in unknown locations in the tall weeds.
“For crying out loud,” he yelled. “Now what am I going to do?”
The man from the mental hospital remarked, “Why don’t you take one lug nut from each of the other three tires to use on the replacement until you can drive into town and acquire the additional lug nuts to make all your wheels secure?”
The Salesman seemed stunned. He said, “Wow! I never would have thought of doing anything like that. That’s an excellent remedy to my predicament. Tell me, what’s a smart guy like you doing in a place like this?”
The patient replied, “I’m here because I’m crazy. Not because I’m stupid.”
