Estelle Costanza


		Estelle Costanza Estelle Costanza (played by Estelle Harris) is the loud and obnoxious mother of George Costanza. Married to Frank Costanza, she and her husband never seem to be able to get along and are constantly bickering back and forth. George partly blames his failures on his parents' strained relationship. Although they were briefly separated, the Costanzas reunite and seem to stay together basically out of habit. However, she and her husband do seem to be able to agree on their dislike of Morty and Helen Seinfeld, because they feel the Seinfelds are snobbish. The Costanzas plan a move to Del Boca Vista in Florida just to spite the Seinfelds.
