Good point

A guy was driving down the street and got a flat tire. He jacked up the car, spun off the bolts and took off the flat tire.

The tire landed on the pile of bolts... and all of them flew up in the air and fell into a nearby storm drain. He sat there fuming with anger. How was he going to put on the spare?

"No problem," said a man leaning out of a window from a building across the street. The building had a sign on the lawn: "Insane Asylum."

He repeated, "No problem. Just take one bolt from each of the other three tires and use them to put on the spare tire."

"That's brilliant!" said the guy with the car. "What are *you* doing in an insane asylum?"

The man at the window replied, "I may be crazy, but I'm not stupid."
