"You're the One Who's Out of This World" is the title of a song that ALF wrote for Lynn, from which he produced a rock video using the instruments that Lynn's boyfriend Scott Maynard was keeping in the Tanner garage.
In the video, ALF dresses as various rock music icons such as Bruce Springsteen, Stevie Wonder, and ZZ Top. ALF sings and plays synthesizer keyboards, guitar, bass guitar, drums, and saxophone in the video.
