Being weird is cool (as long as it's not gross weird). People will certainly remember you, because you're different than most other people they meet. That can actually be a good thing, so don't let it bother you. If your weirdness can be interesting or funny, that's even better. You just need to be comfortable with the fact that you aren't stamped out of the same mold of 'normalcy' as all those other clones. It's not just okay to be different, sometimes it's great.
Remember, Rudolph the Red-Nosed Reindeer was weird, too, until it turned out his weirdness was useful. Then he was a hero.
(okay, I know he's fictional, but how often do I have an excuse for using that emoticon?)
Albert Einstein was weird, just look at that hairdo - nobody's making fun of him now, eh? Well, maybe sometimes, but they still respect him.
Just don't pick your nose in public, or keep collections of boogies. That's gross weird and you don't want to be remembered for stuff like that.
