I don't really get into confrontations, but I had one that was pretty damn memorable:
I play the cello (for anyone who doesn't know, imagine a violin, but about 5 times larger), and am one of 3 people in the school, so we tend to attract a bit of attention.
Anyway, a typical tosspot at the school (build of a brick shithouse, about 6ft, ugly as a month-old turd) had made it his goal of sending me over the edge before the end of the year. He'd tried thwoing stuff at me, stalking me, sending crap to me over school e-mail, and anything else someone like his would try. Eventually he took it too far, and broke into my locker and stole some of my stuff, including a small carrybag, containing some diabetes things. I ran into him a few days after the incident, and he held up the carrybag and laughted at me, saying that I'd never get it back, not realising my cello was right next to me.
I had a hard case on my cello, to protect it, and thank God that was on when this happened. I grabbed the cello by the area around the neck and spun it around the bastard, smacking him in the knees, and anyone who's played a cello knows how damn heavy they are, and how solid the hard cases are. He went sprawling onto his back, upon where I turned, took the bag back and walked off smirking to myself.
Sadly, no-one was around, so the story wansn't spread.
