There's an old story about a guy with a flat outside a nut house.
He's changing the tire, has the lugnuts in the hubcap. A nutcase is hanging on the fence, drooling, blubbering, making small sounds. Gets the guy kinda nervous. He steps on the edge of the hubcap, lug nuts go flyin into the tall weeds.
The guy's stumped.. middle of 'nowhere' outside a nutfarm, flat tire, good spare but no lugnuts. The nutcase says in a level tone of voice, 'take one nut from each of the other three wheels.. that'll getcha into town.'
The guys thinks for a second, sez, 'hey.. that'll work... good idea.' Then he asks the looney why he's in a nutfarm.
"I'm crazy. Not stupid."
