Plot summary
Lois and Hal visit Francis to help him celebrate one year of sobriety, but when they attend his A.A. meeting, they find out that he pretended to be an alcoholic so he can tell the other, actual alcoholics about how Lois was a bad mom to him. Meanwhile, Malcolm and Reese find the spare key to Hal's car and plan to spend the evening terrorizing the neighborhood, but when they refuse to drive Dewey to the arcade, he swallows the key.
