Crazy but not stupid …

One truck driver was doing his usual load delivery at a mental hospital, by parking his vehicle beside an open drain.

He discovered a flat tyre when he was about to return from the mental hospital. He jacked up the truck and removed the flat tyre to fix the spare tyre.

When he was about to fix the spare tyre, he accidentally dropped all the four bolts in the open drain.

As he could not fish the bolts in the open drain, he started to panic as to what should be done.

Just then, one patient happened to walk past him and asked the driver as to why he was looking troubled.

The driver thought to himself, since there was nothing much he could do, he could as well humor the loony guy.. Just to keep the bugging chap away, the truck driver informed the whole episode to the mental patient and gave a helpless look.

The patient just laughed at the truck driver and said "you  cannot even fix such a simple problem? No wonder you are destined to remain a truck driver for life".

The truck driver was astonished to hear such a compliment from a mental guy.

"Here is what you can do" said the mental guy.

"Take one bolt from each of the remaining three tyres' wheels and fix them on to this tyre. Then drive down to the nearest workshop and replace the missing ones. Isn't it simple my friend?"

The truck driver was so impressed with this quick fix answer and asked the patient, how come he was so smart and intelligent but still at the mental hospital?

The patient replied..."Hello friend! I stay here because I am crazy but not stupid".
