A man with a flat, in a driving rain, stops in front of a sanitarium. He gets out, proceeds to jack up the car, pops the hubcap and takes the five lug nuts off the wheel. After pulling the wheel, he takes the flat to the trunk and retrieves the spare, but on the way back, kicks the hubcap, and all five lug nuts spill out and are washed into the drain. Soaked to the gills now, he starts to swear, asking out loud what he is going to do to get home.

A voice says "Hey." He looks up to see a face peering through the wrought iron fence, and the guy says "What?"

The man inside the fence tells the car owner "Take one lug nut off the other three tires, and put the spare on. Then go to an auto parts store and buy five lug nuts to replace the ones you lost."

The driver is stunned. "Hey, man, you're pretty smart. Why in the world are you in there?"

The man replies "I'm in here because I'm crazy, not because I'm stupid."
