Seinfeld, 'Estelle Costanza' (1993-1998)

Creators: Larry David and Jerry Seinfeld. The character of Estelle Costanza, performed by Estelle Harris in the NBC sitcom Seinfeld, personifies kvetching in its purest form. She does not kvetch about anything specific. Kvetching is an intrinsic part of her nature. No matter how good something is, Estelle will be able to find fault.
