Joke

After having a flat tire in front of a mental hospital, the driver was busily removing the lug nuts and putting them in the hub cap when it tipped over and all the lug nuts fell down the drain.

Psst. Hey Mister.

The driver looked up and saw an inmate looking at him through the iron bar fence. Don't let that bother you. Just take one nut off each wheel and put it on the tire you just replaced.

That is brilliant. I thought this is a mental hospital, so how did you think of that?

Look, mister, I may be crazy but I ain't nuts.
