Now anyone that hasn't heard of this guy is in for some real kicks.

For a background on this guy, this isn't meant to be derogatory toward anyone who has disabilities. Additionally, it is said that he has a mild form of Tourettes, seemingly corprolalia, which affects 10% of the population with Tourettes: http://www.medterms.com/script/main/art.asp?articlekey=12349

Furthermore, it is obvious that most of the video is scripted, he is after all, a paid actor. But you could tell that he does have it, he has certain tics and expressions that are distiguishble. So even if most of it is just acting, he's funny as hell.

Oh yeah, and here's a letter from http://emailsfromcrazypeople.com/
