When mind bendingly drunk and pissed off I elbowed my way through a car rear window. I'd tried to punch through first but that hadn't worked and just hurt my hand. Yeah, that's a period of my life I regret. Glass hurts.
On a different situation at a party a group of lads were being complete tossers to me, I was drunk (I know...) and so wanted to fight them. Yeah, them. This was obviously a bad idea and with the help of my friends and a persistent but small voice of reason I just walked away. Trouble was I was still drunk and epic-ly pissed off and had no release of tension, fight/cry in other words. So I decided to take my frustration out on a wooden fence. I managed, after about a minute or two, to punch my through it. My hands, unsurprisingly, were in tatters.
Moral of the story, I have anger problems and shouldn't drink so much.
