Worst thing you've ever done

Hit some kid on the head really hard with a wrench. I also threw a rock at my teacher's eye.

Tarnished the innocence of a really sweet girl (her mouth more specifically). Ahhhh teen years.

I can neither confirm nor deny that I was involved with and incident that caused a significant amount of damage to both a Mercedes and a BMW, the latter of which was not meant to go on the market for another year. I can also neither confirm nor deny that I damn near pissed myself after the previous incident... which can neither be confirmed nor denied on whether or not it actually happened.
