So, what's your biggest dummy moment??

ok here is one that will make you smile.
back in high school when I was working a long shift pumping gas I got home about 2:30 3:00 am I had a few beers and was working on my 67 chevy II ss that I put a new sun tack in. so I was working on the wiring for the tack I put in that morning before school after getting most of the wires set I was still under the dash and hit the key well I forgot the ground wire was in my teeth well that woke me up and killed my buzz
