Little Joke for you
Anyhow.. here's the joke to illustrate that :)
A guy gets a flat tire and stops to put his spare on... he notices he's stopped in front of a mental institution and there is a patient observing him from inside change his tire.
Guy proceeds by taking off the bolts and places them in the hubcap, carefully to make sure he doesn't missplace any of the bolts, he goes to grab his spare tire in the trunk and just as he does, a car zooms by at high speed and causes the hub cap to tip over and the bolts go flying everywhere. AS much as the guy looks for them, he can't find a single one... so he's standing there on the side of the road wondering what the hell he is going to do.
Then the mental patient that was obsverving him taps on the glass and signals to come near.... The mental patient suggests to the guy a solution "Why not take one bolt from each of your other 3 wheels and put them on the spare tire, that should be good enough so you can drive to the nearest car shop and buy some bolts"... The guy replies "Wow, that's an excellent idea, thanks!" but with a puzzled look on his face. The mental patient replies to him "Well if you like the idea, why the expression on your face?". The guy says "Well you're the one locked up in a mental instution and yet you're give ME advice".
The mental patient replies " I may be CRAZY, but I'm not an IDIOT!".
