Mrs. McBadbat

Background
This woman is Chester's mother and Bucky's wife. She has never made an actual appearance on the show, but a picture of her is shown in Chester's trailer. She was mentioned again in another episode when Chester looses a tooth and Bucky says: "Without that tooth you look like your mother!". Her fate remains unknown because Chester and his father live alone.

Description
Like her husband, she wears a paper bag over her head, obscuring her identity. She likely did this out of shame of being married to the worst baseball player in history.

Trivia

 * Her fate is never explained on the show, although neither Bucky nor Chester ever refer to her in a past tense, suggesting that she is still alive.
