51. Mr. Kruger
Best-known episode: "The Strike"
After George gets fired from the Yankees, he goes to work for the head of Kruger Industrial Smoothing (noted for botching the Statue of Liberty job because "they couldn't get the green stuff off"). Though the deeply apathetic Mr. Kruger only shows real interest in nicknaming his employees, he's a catalyst for one of the greatest contributions to the Seinfeld lexicon when he catches George accepting donations for a fake charity, the Human Fund. George explains that he was really just protecting his belief in Festivus, a holiday his father made up — and invites his boss to his parents' house to prove it. Mr. Kruger gets to partake in the traditional Airing of Grievances and viewers are introduced to a Festivus for the rest of us. CADY DRELL
