Kanker Sister's Mother

The Kanker Sister's mother is often mentioned in the show. She obviously dislikes men (referenced in the episode: "Don't Rain On My Ed" when Lee says: "Mom was wrong, men do amount to a pile of dirt.") And she might be hypersensitive or bad-tempered, maybe even both (And this was referenced in "Hanky Panky Hullaballoo" when Marie gets her face tromped on by May and then sayd: "Now I know who got Mom's genes.")
