Step by Step - Season 3 - Eps 6: Video Mania
Mark is depressed about getting an ""A"" on a test, rather than an ""A+."" Frank tries to loosen him up by getting him a video game. Mark does loosen up, but his grades slip, he starts fights, and he becomes addicted to the game. Frank and Carol send him to a support group. There, he recognizes his addiction and begins to work it out. In the meantime, Cody goes to the health food store to obtain a cure for his cold. In the parking lot, he buys a booklet teaching him how to cure himself with the powers of his mind. Dana mocks him, despite the fact that using his newfound powers enable Cody to think of Karen wearing a turtleneck to hide her hickey. Dana, however, when she is unable to get rid of a cold, tries it herself (when no one else can see, of course).
