22. Lloyd Braun
Best-known episode: 'The Gum"
George never could compete with his nemesis Lloyd Braun — at least not in the eyes of Estelle Costanza. She kept comparing her son to Lloyd while he was growing up. And even after Lloyd spends time in the nuthouse — he got there by saying "serenity now" until it drove him insane — Estelle still wishes George could be more like him. ("Good for you, Lloyd!") He works for a failed mayoral campaign in "The Non-Fat Yogurt," supplies Chinatown chewing gum in "The Gum" and almost wins a prize Waterpik selling computers for Frank Costanza in "The Serenity Now."
