Strong Arms of the Ma

Marge gets mugged outside the Kwik-E-Mart and she starts feeling vulnerable and becomes scared to leave the house.  Dr. Hibbert diagnoses her with agoraphobia.  The family tries to help her get back out of the house, but their efforts drive into living in the basement.  In the basement she finds their unused weight set and she begins working out.  Two weeks later she is stronger than she ever was and realizes that she can leave the house.  In fact while celebrating her release from her fears, she confronts and beats the crap out of her mugger.  While out working out, Marge runs into Ruth Powers, the neighbor she once went on the lam with.  Ruth tells her about how steroids can help her to get bigger.  Marge starts taking the supplements and gets into a women's bodybuilding competition.  She takes 2nd place, which only entices her to do better next time.  At Moe's she tears the place apart when she suffers from steroid rage.  Homer makes her realize that she has become everything that she can't stand and she destroys the weight set.
