3. Florence Johnston
Florence Johnston (Marla Gibbs) probably ran her mouth more than she ran a vacuum cleaner on the hit 1970s sitcom, "The Jeffersons." The sassy housekeeper and her boss, George Jefferson, gave the show some of its funniest moments with their constant bickering. Florence later ‘moved on up’ to her own spin-off, "Checking In," but the show was quickly canceled.
