The difference between CRAZY and STUPID

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

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

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

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

Because he couldn't fish the bolts out, he started to panic.

One patient happened to walk by and asked the driver what happened.

The driver thought since there's nothing much he can do; he then told the patient the whole incident.

The patient laughed at him and  said "you can't even fix such a simple problem... No wonder you are destined to be a truck driver....

Here's what you can do; Take one bolt from each of the other 3 tyres and fix it onto this tyre. Then drive to the nearest workshop and replace the missing ones. Easy as that"

The driver was very impressed and asked "so you're so smart but why are you here at the Mental Hospital?"

Patient replied: "Hello... I am here because I'm CRAZY, not because I'm STUPID!"
