The most loved character that was never seen on camera in the history of television. Yes, it's Peg's mother, Grandma Wanker.
SEASON 1, EPISODE 7: Peg's mother is a woman of great sophistication: we learn in this episode, the first mention of her, that she won the Keg Sucking Contest at Beer Fest '87. Her talents are limitless.
SEASON 2, EPISODE 1: Grandma Wanker weighs in at 200 pounds. She must have been dieting. She is still heavy enough to wreck the Bundy's fence, although it doesn't help that she had a keg under each arm. Must have been practicing for Beer Fest '88.
