Jackie Martin is the wife of Glenn and mother of Conor and Courtney. She is often stressed with the problems involved in raising a family in an RV.
Jackie Martin befriends the circus strongwoman, Olga and decides to take up a training regime. Unbeknown to her, the strongwoman slips in a cheat card: steroids. Thus, when Jackie finishes her very brief workout, she immediately removes her jacket to reveal huge guns and chiseled abs. She still retained her beauty in the facial department (and believed herself to very much be an Amazonian Beauty), but she sported a deepened voice and increased aggressiveness as a result of the roids (at one point, she strips Glenn—who has an Oh, Crap expression—down to his underwear and then tells him to hang on to the bedpost as she forcibly has sex with him). Most characters seemed to ignore her muscularity, but those who didn't always mistook her for a man, earning them a punch from an offended, violence-prone Jackie. At the end of the episode, she walks into a men's bathroom and checks herself out, commenting that she's hot, but then two guys mistake her for a guy again, and Jackie finally agrees with their sentiment that she's unattractive. By the next episode, the muscle (and all of the other negative side effects) is gone.
