How Do I deal With IDIOTS?!?

Alright...

So pretty much, I'm a guy in high school. That speaks volumes about the kind of things that I'm experiencing right now, and I probably don't even need to go further into explanation. But I will, just because I know you all want me to...

Essentially, I get along with most people in my class, and in my grade. However, every years, there's a group of somewhere between 1 and 5 people that just consistently piss me off for various reasons. Right now, there seems to be only one kid that's been doing that this year. He's some sophomore kid in my math class (I retook Algebra I my freshman year because math is not my strong point at all), and just keeps blurting out crap about me, virtually every time I say something. He's also in my German class, and occasionally says moronic stuff in there as well.

I don't really know why this idiot is centering in on me - I'm a bit different in the fact that I actually have a brain, and use it. I argue a lot with my math teacher because I don't think that the probability formulas and problems we do are at all accurate and realistic, but that's about it. I mostly just talk with the people at my table, and not the people where this kid is, on the other side of the room.

I almost wrung his neck because of a stupid comment he made about my hair - for some reason, we got into a discussion on that subject, and I mentioned that I spend a bit more time than average on my hair than most guys, and he said it was "time wasted" or something. I have no idea where that comment came from, and I have no idea why he decided to butt into the conversation that people in my area were having. I'm a relatively self-conscious person, so that only pissed me off. It's nothing major, but he just keeps throwing in his obnoxious little two cents worth EVERY time I've said something the last two weeks, and it's just been making me more and more angry. I'm normally a nice and polite person, though I can have a House-ish sense of humour - but I always make sure people know I'm just kidding with them. In all honesty, I don't even think I've uttered a single sentence to this kid.

In my German class, he made some idiot comment about me being a "gangster" because my pants had a lot of zippers on them - I shop at Express, for God's sake, I don't know how virtually anything there can be counted as "gangster". Maybe he could say that if I was wearing FuBu stuff, or South Pole, but I wouldn't be caught dead wearing that trash. And he was over there today, sitting in baggy shorts wearing a stereotypical wankster DC "gangsta" shirt with his hoody up.

So I'd really like to just knock his teeth in. But there's a wee bit of a problem - I've been on probation for about a year, and most people don't know it. I used a firearm to rob a large number of houses, stole cars, etc. Relatively dumb period in my life, and I got arrested after I got emotional and angry - I have a tendency to let my emotions get the better of me when I'm angry, and I've been trying to repress those stupid decision making processes. This kid thinks he's badass or something because he can talk trash to somebody that'll be locked up if they do anything - he doesn't know that, of course, and I don't really want him to. I'm not proud of what I did, but honestly... I don't see what kind of idiot would talk like he does to someone they don't even know, especially when if they had asked about me, they'd've found out that if I'd been a year or so older at the time of my arrest, I'd've gone to prison for well over 60 years, for the events of about one night.

I've gotten over all that, and I actually care about other people now. I'm a socialist - whether you agree with that or not, I don't care. But I care about the welfare and well-being of other people, and now certainly think there's something twisted about stealing from working class people - not that I'd really steal or rob at all any more.

I want to close this up, before I ramble off track, however. Summed up, I just want to know what to do or say to shut this dick up. I'm not a big or scary muscly guy or anything, but I honestly don't know what I'd be capable of if I had a hold of a ballpoint pen and went out of control. Not to sound tough or anything, but really...

I know everyone just says to punch kids that do stuff like this, but in my case, I can't. Alternatives, anyone?
