George Louis Costanza (Jason Alexander) is a character on the unconventional sitcom Seinfeld. He is best friends with Jerry Seinfeld (Jerry Seinfeld), both of whom are main characters with Kramer (Michael Richards) and Elaine Benes (Julia Louis-Dreyfuss.)
George is the neurotic one within the group. He comes from a family, who is equally as neurotic. He is often called out (by his three friends, especially) for making a fuss about everything as well as having his own rituals and morals which others do not seem to follow. Everything from his relationships to his image to his daily routine is crippled by this constant neurotic complaints and actions his insists upon every day minutiae.
