8. Tobin Bell
Known for: The "Saw" franchise
Seinfeld Appearance: "The Old Man" Tobin Bell is probably a name known only by horror fans as the actor that played the Jigsaw killer in all seven "Saw" films. As Jigsaw, Bell punished those that didn't truly appreciate the lives they had. Perhaps it was his run-in with the "Seinfeld" gang that led him on this path... Bell played a record store owner in a 1993 episode that gets into a confrontation with Kramer and Newman. The goofball duo had just plundered an old man's vintage record collection and brought it to Bell for cash. When he lowballs them with his offer, Kramer and Newman insult him and inevitably it causes a physical confrontation, destroying all the records. It can be said that the core group on "Seinfeld" didn't truly appreciate their lives, constantly nitpicking every small detail they noticed. But I think it'd be an overreaction to place them in an elaborate life-or-death trap.
