If it makes you feel any better, I was showing a friend how good I had tuned up a F d pu, and reached in the cab, bumped the key, she lit off and was in granny gear, the front went thru the wall and the wheels dropped off the edge onto the frame, and I got the key turned off. I don't remember ever being that embarrasssed. That happened in 1981 and my face flushed whilw typing this! Don't feel too bad!!!
