Wayne's brother Randy Rude the Science Dude comes to town with his show. He invites Wayne to help him get the ratings up. Wayne agrees to help but unknown to him, he started taking over. When he realizes this, he plans a way to pay back for all the times that he has taken over.

Wayne invents a pair of glasses to watch the solar eclipse with his family. Somehow he can see the future with the glasses. The rest of the family members are having trouble getting to the eclipse. Amy loses her note, the bus breaks down for Nick, and Diane is in a dog case. Wayne sees the future where his family is nearly killed. Can he save them in time?

Amy wants to get into college, and Wayne wants to help impress the recruiter who's coming to dinner at the Szalinski house. Worried about being embarrassed by her family, Amy convinces Diane to talk to Wayne about acting normal during dinner. Diane talks to Wayne while he's working on the Psycho-Cybernetics Generator, a machine that makes one's thoughts happen in real life. Diane blurts out that she wishes they were a normal family just as she's zapped by the generator. The next day Diane becomes frozen in time and, lost inside her thought of a normal family, learns that normal can be boring. Worried that Diane might not know she's trapped in a dream, Wayne wires them both to the generator, which projects his thoughts into Diane's head. If Wayne can join Diane in her thought, he can help her get back to her very non-normal life.
