A traveling sales man was driving past a mental institution when all of a sudden his right front wheel came off, went off the road and came to rest against the tall metal fence with the two coils of razor wire at the top.
As the tire came to rest on the fence a male patient came over and sat down Indian style inside the fence to watch.
The driver of the car was terribly distressed. When he came over to the fence to retrieve his runaway wheel and tire the patient asked, "What's a matter buddy?"
"All of the lug nuts had came off the wheel and it will be impossible to find them and I don't know how I will get home tonight."
The patient said from the OTHER side of the fence said, "Well, If I were you, I would take one lug nut off of each of the other wheels, put my right front tire back on my car and drive away."
The Salesman was shocked when the patient said that and asked him "How did you figure that out?"
The patient smiled at the salesman and said "I'm in here because I am crazy, not because I am STUPID!"
