Dumb things that you did.......because you didn't know any better.

Work related, gas stations and Sears auto center.

1) I had gotten pretty good at giving a hot radiator cap a little twist to the first stop and jumping back while the steam flew. One time the cap came completely off and the rad pretty much exploded in my face. At least I got the rest of the day off.
2) A guy came in and needed an alternator. Pulled the car in the bay, loosened up the alternator bolts, and it dropped down on the bracket until the battery terminal hit the block and stopped it. I watched the cable burn like it was in slow motion.
3) A cow-orker pulled a car in, told me the engine was dying. So I go over, pop the hood, pull the cap, and grab the rotor to remove it. Cow-orker had left the key on. Lucky me the rotor pulled up off the distributor but still knocked the crap out of me.
4) Was working on a car, trying to figure out if it had jumped time. Had the plugs out cranking it. Fumes built up in the engine compartment until a spark cleared them out. Was having trouble putting the fire out until I realized the oily floor under it was what kept sparking up.

you sound lucky to be alive....lol
