A truck driver was doing his usual delivery to Mental Hospital.

He discovered a flat tyre when he was about to return home.

He jacked up his truck and took the flat tyre down.

When he was about to place the spare tyre on he disturbed his locking nuts which rolled into the adjacent drain.

As there was a fixed steel grill over the drain, he started to panic.....

One patient happened to stroll past in the Hospital grounds and asked the driver what had happened..

The driver thought to himself, since there's nothing much else he can do; he told the patient the whole story..

The patient laughed & said: "A truck driver who can't even fix such a simple problem......here's what you can do...."

Take one wheel nut from each of the other three wheels and fix them onto this wheel....

Then drive to the nearest workshop and replace the missing ones...easy as that!".......

The truck driver was most impressed and asked:.."You really are smart, ...but why are you here at this Mental Hospital?"

Patient replied:...Hellooo,... I stay here because I'm crazy but I'm certainly not STUPID!".......
