I MAY BE CRAZY
A driver traveling down an unlit side road at night gets a flat tyre, beside a tall concrete fence allongside the road.
When he gets to replace it with the spare, he notices a faded sign on the fence, just readable in the starlight, saying:
STATE MENTAL ASYLUM.
DON'T PARK HERE!
DON'T PARK HERE!
The wall stretches away beyond the reach of sight in both directions. There are no gates visible.
He nervously but carefully starts make the repairs.
Taking off the hub cap and wheel nuts, he puts the inside the cap for safety.
However, just when he is ready to put them back on, he hears a cough above him on the wall.
He jumps up in panic and steps on the hub cap causing four of the wheel nuts to fly out into the grate of deep drain in the gutter of the road.
The diver looks up hoping it's one of the asylum staff, just checking what he's doing there.
But what he sees is manically smiling face wreathed with long greasy hair, just staring at him without blinking.
It sends shivers down his spine.
The wall is not high enough to prevent someone jumping down from it, especially someone not thinking straight.
He immediately starts trying to find a way to get the nuts back.
First he shines his torch into the grate looking for the nuts, but they are too far away to see, and the grate is welded shut.
The inmate just keeps staring.
He tries his phone to call for help, but there's no signal.
The he tries several other ideas to get the nuts out of the drain, but nothing works.
Finally he starts to consider if it would be safest to walk around the wall looking for the entrance, or just look himself in the car until morning.
Then the inmate asks:
"Why don't you just take a nut off each of the other wheels?
Then you would have four nuts per wheel and be able to drive to a garage and buy four more."
He looks up at the inmate with shock.
The inmate laughs and says:
"I may be crazy, but I am not stupid!"
