The "Saved by the Bell" star Dustin Diamond was arrested early Friday morning on weapons charges in Wisconsin. The 37-year-old actor, who shot to fame playing the goofball Screech on the hit '90s high school sitcom, was busted for possession of a switchblade, first degree recklessly endangering safety and carrying a concealed weapon, In the years after his "Saved By the Bell" heyday, Diamond has become a punch-line for all the wrong reasons -- filing for bankruptcy in 2001 and releasing a sex-tape five years later.
