Screech! What happened? Arrested for what? A switchblade? Say it isn't so - We have the video.

Dustin Diamond - the D Man - as he calls himself is a little a lot off his rocker. Allegedly he got into a bar fight over the holidays and defended his gf's honor with a switchblade.

Screech  also had this Celebrity Fit Club blowout with Sgt. Harvey Walden. Although NSFW, it's a pretty awesome yelling match.
