The stupidest thing I have ever done...

Younger days, dating a girl whose brother was a complete moron, sweetie promised me the world if I help her brother get his car started. Pulled the car over to my dad’s garage and whittled the problem down to a bad starter, easy enough I changed it out. Battery reconnected and I told him pump the gas a few times and give it a try, nothing, no click nothing. Rechecked my connections, and said to him,” Are you sure you have it in neutral”? Well I heard him shift the linkage around, and I thought I will jump the starter to make sure I didn’t get a reject one. Jump it…it started…then it lunched forward into my dad’s workbench and pushing me off to the side of the car. I jumped up, and reached my arm through the window to turn off the ignition switch, he sat there dazed and confused. Really little damage was done other then I nailed the leg back on to the bench. Worst then that, I never got what I was promised!
