Estelle Costanza, Seinfeld
Played by Estelle Harris
Overbearing? Check. Shrill? Check. Critical? Check. Funny? Oh yes indeed. Georges mother was a Freudian nightmare who never failed to humiliate her son, and she is clearly at the root of his problems. She was known to hinder his dating life on occasion. When she caught George pleasuring himself in her house, in the classic episode The Contest, she fell over in shock and landed in the hospital.
