I have a sad true story about a friend I grew up with, and lost track of while I was in the Army. We were always working on cars, and if a car didn't start, the first thing he did was put gas down the carb. A few years back I found out that he moved to NC, and was killed when he caught on fire working on a car. I don't know for sure, but that was the first thing I thought of when I heard that. While this pic is funny, I'll bet this really does happen more than you think.
