What stupid things have you done?

Lets see, transmisson in the engine on a motor grader, caught it before starting it! I was once pushing a mower (the older gas ones without the engine kill/stop brake) and saw a wire I was just about to run over, idiot here reached down to pick up the wire and the mower caught some of it and almost yanked my hand into it, I about passed out! I took a bath the other day in hot transmission fluid as in hair, face and clothes. Synthetic oil no less. Oh yea, my 69 340 Swinger that has been painted for 12 or 14 years now and NEVER been on the road, well it's parked in the garage under a cover, I had to move a dryer out of the garage into the house and while doing that I managed to scratch the top corner of the right fender that has never been out. Made me almost cry. And it's still sittin like that. And the list could go on.
