Maniac Mansion

Harry is stuck inside the mansion in a parody of Home Alone. Most of this episode is Fred explaining what Maniac Mansion is about. He tells stories of pilot episodes, and how the show developed from there. He then meets Casey and Idella, and finds out that the script has changed so that only Harry is in it. He's angry and tells Ike and Turner that they have to write themselves into their own script. Later, Tina comes by and makes him realize that the show is about everyone through flashbacks of the first season. At the end, the family decides that they need to make it look like a television show again. They have Fred wake up from a nightmare about his family being a TV show, as they sometimes did in the first season.
