Thought it might be interesting to start a thread about dumb things you've done in the garage, shop, etc. while working on a vehicle. Maybe we can learn from each others mistakes.
My list of notable mishaps:
1. Grabbed a hot brick with my bare hand (had been using it to weld on with a torch).
2. Sprayed myself in eyes with self-etching primer (was trying to adjust the fan-spray tip).
3. Lit my shorts on fire with a welding torch (same day as primer incident, that was a bad day).
4. Had a 12" "jobber" spade drill bit bend 90 degrees at the chuck, swing around, and almost cut open my stomach (it was slightly bent and I didn't notice until it was too late).
5. Cut the tip of my knuckle off while filing a sharp edge on a piece of sheet metal in the vice.
6. Tons of other random cuts, smashes, burns, etc.
What's everyone else's stories?
