Wise Suggestion

A man had a blown tyre next to an asylum. While changing the tyre, he noticed a patient leaning over the wall looking at what he was doing with keen interest. Before he could replace the wheel, he realised that all four screws had rolled down the slope, dropped into the drain and could not be retrieved.

While pondering what to do, the patient suggested that he took out one screw from each of the other wheels to fix on the last wheel. In this way he would be able to drive to the nearest gas station to have his problems fixed.

The man was naturally impressed and complimented the patient for his wise suggestion. The patient replied, "It's nothing, actually. You see, I may be mad, but I am not stupid!"
