The flat tire
Okay, before the days of mobile phones this guy is driving along a lonely country road on his way to an important meeting in the next town and just as he is passing an insane asylum he gets a flat tire. So he pulls over next to the steel bar gate and jacks up the car, pulls off the hub cap and then unscrews the four nuts that hold the rim to the axle, puts them in the hub cap on the ground and when he goes to get his spare tire he accidentally kicks the hub cap and the nuts fall down the sewer. 'Oh my God', he thinks, he will miss the meeting and lose his job. How can he drive the car with only 3 wheels? Then he hears a voice from behind the gate.
"Looks like you got a problem there."
He answers, "You don't know the half of it."
The voice says, "I'll tell you what to do, just take one nut off of each of the other three wheels and put them on the spare when you mount it. That will get you to where you're going, and later on you can replace the missing nuts."
"Hey" he says, "That's a great idea. Are you a staff member there?"
"Nope, I'm a patient."
"You're a patient?" the man exclaims.
"Yep, I may be crazy, but I'm not stupid."
Sometimes you have to be crazy to see the obvious. Let's hear it for the crazies!!!
Bravo, three cheers for us crazies.
