Once the audience is introduced to the remainder of the Costanza family (Frank and Estelle Costanza), the reason behind George’s mannerisms and/or responses to everyday situations becomes slightly more explainable. For the majority of the Seinfeld series, George lives at home with his parents due to consistent unemployment. Thus, his wacky parents have a huge effect on how the audience views George, enhancing the hilarity.
Frank Costanza – The Anger
Frank Costanza is known in the series as a very angry man. He is constantly yelling in a fit of rage no matter how big or small the issue at hand is. Being the stereotypical stern father, Frank takes the role role a step further and picks on George and his lack of employment, knowledge, common sense, etc.
Estelle Costanza: Latvian Orthodox? Why are you doing this?
George Costanza: For a woman.
Frank Costanza: A woman? What are you out of your mind?
Estelle Costanza: Why can’t you do anything like a normal person?
Frank Costanza: Wait. Is this the group that goes around mutilating squirrels?

Estelle Costanza – The Neurosis/The Questioner
Estelle Costanza is George’s mother, repeatedly questioning the motives of her husband, others, and, for most of the time, her son, George. Estelle always seems to be in doubt whenever George seems to succeed at something, i.e. being a writer for a television show in “The Pitch” (4.3), getting engaged to Susan in “The Engagement” (7.1), etc. In the episodes “The Contest” (4.11) and “The Outing” (4.17), Estelle is injured in some sort of “freak accident” both times she discovers “something sacred” about her son, she guilt trips him the entire time she is in the hospital. She consistently reminds George that he is a failure, an issue, or crazily immoral.
Overall, George’s parents can be blamed for his lack of sociable manner in the outside world. The anger (Frank) and the neurosis (Estelle) combination that George not only grew up with, but also experienced throughout his adulthood while living with his parents, are an influence on his pathetic nature in everyday life. The childish way that Frank and Estelle treat their living-at-home son adds another element of humor to George Costanza.
