http://www.imdb.com/title/tt0374900/Character Kip is wearing braces to make him look dorkier
http://filmforce.ign.com/articles/537/537199p1.html"Q: I talked with Jon [Heder] and he mentioned that you totally didn't like wearing your hair like that – the comb-over.
RUELL: I thought it was great for the character. I mean, even the wardrobe. And I made the mistake of suggesting that Kip get braces. And when I made that suggestion, I just assumed that we'd be able to Hollywood it up and there would be some temporary things I'd put in while we were shooting and I'd just kind of take them out. And then flash-forward to, you know, showing up at Jared's place a week before shooting and I'm in the orthodontist's chair getting real braces attached to my teeth. (Laughs)"
