36. Jason Hanky
Best-known episode: "The Apology"
James Spader has played his share of villains. (Like in the indie thriller 2 Days in the Valley, which must hold some kind of record for casting Seinfeld one-shots — the film also has Teri "Sidra" Hatcher and Lawrence "Alton" Tierney.) But Spader's Jason Hankey is the kind of creep who refuses to loan George a sweater because he doesn't want George stretching out the neck hole. When Hankey joins a 12-step program, George demands a Step Nine apology for the neck hole incident, even if he has to make a scene at Baskin Robbins. ROB SHEFFIELD
