5. Peter Stormare
Known for: "Fargo", "Prison Break", playing a bad guy in just about everything
Seinfeld Appearance: "The Frogger" This entry is a bit interesting because by the time Peter Stormare appeared in this 1998 episode of "Seinfeld", he had already played a major role in the Coen Brothers' hit "Fargo". In that, he played a cold, tacit killer that got so frustrated with Steve Buscemi's character that he chopped him up and fed him through a wood chipper. In "The Frogger", Stormare plays small-time crook Slippery Pete. Kramer recommends him to George for the dangerous task of... transporting a Frogger machine from one place to another without draining the battery, thus wiping the high scores. Throughout the episode, an oily Stormare is confused for a serial killer by Jerry, enjoys a game of Frogger, and bickers with Kramer for stealing his mail-order bride. Careful, Kramer. Don't get him too mad. He's got wood chipper access. Speaking of "The Frogger"...
