"I'm in no condition to drive...Wait! I shouldn't listen to myself. I'm drunk!"
---Homer Simpson
Towards the middle of this episode, Marge is caught drinking and driving. The viewer knows that Homer was really the one who had been driving under the influence. When the car crashed, he moved Marge into the driver's seat and ran away so he wouldn't get his license taken away. Marge, who is unaware of this, believes herself to be an alcoholic and enters rehab for alcoholism.
After learning that Marge would be gone for 28 days, Homer drives straight to the rehab center. He confesses to Marge that he had been the one driving that night. Marge is furious, and stomps back to her support group. She exclaims, "I need a drink!" to which Agnes replies, "Well you're lucky you're in rehab." Each member of the group pulls out a hidden bottle of alcohol and Marge ends up having five drinks.
On the verge of drunkenness, Marge realizes that she is not happy. The only time she had been happy was when she was drinking with Homer. After this realization, Marge tells the group that she is a, "Homerholic." An interesting dialogue occurs after this statement. Otto asks Marge if he can have some "Homerhol," but Marge reveals to him that what she's addicted to can't be drank, snorted, or smoked. Otto ponders this for a moment, and then replies, "Hmm. Then you'd better inject it between my toes 'cause my mom checks my arms!" I think this shows that codependency can be a major problem for addicts. Not only is Otto an alcoholic, he is also a drug addict. It is a serious problem, but on the Simpsons, it is projected in a humorous way.
