George Louis Costanza is a fictional character in the American television sitcom Seinfeld (1989–1998), played by Jason Alexander. He is a short, stocky, balding man who struggles with numerous insecurities, often dooming his romantic relationships through his own fear of being dumped. He is also remarkably lazy; during periods of unemployment he actively avoids getting a job, and while employed he often finds ingenious ways to conceal idleness from his bosses. He is friends with Jerry Seinfeld, Cosmo Kramer, and Elaine Benes. George and Jerry were junior high school friends (although in "The Betrayal", Season 9, Episode 8, George says the two have been friends since fourth grade) and remained friends afterward. George appears in every episode except "The Pen" (third season).
