Kim and Craig have written a musical for their highschool. When they have casting problems, they get Lucy and Harry to perform in their play on the theme of the generation gap.
Lucy and Harry wind up playing the parents, to Kim and Craig as the kids. They perform many sketches through the centuries showing how the generation gap has changed through time. They parody relationships in Roman times, the "Gay 90s", and the future space age.
Special Notes: One of the most original musical episodes of the series with extravagant sets and enjoyable songs by Lucy, Gale, Lucie and Desi. Lucy's part was again dubbed during the songs.
