There are at least four different versions of this episode:
- Original Broadcast version - ALF loses his memory by using an electric mixer in the bathtub and electrocuting himself. Complaints from parents caused the scene to be changed. Also, the flashback clips feature their original on-set audio. This creates problems with aural continuity, because halfway through season one, Paul Fusco changed Alf's voice from being deep and raspy to a higher, friendlier-sounding pitch; therefore, Alf's voice in the flashbacks doesn't quite match his voice in the new footage.
- Second Broadcast version - The electrocution subplot is replaced with ALF losing his memory after slipping and falling in the bathroom. This version appears on the Region 2 DVD release.
- Syndicated version - Removes several scenes (including a subplot with Judy Landers) to make room for extra commercials, and the flashback audio is partially re-recorded with the "new" Alf voice.
- Region 1 DVD version - A bizarre hybrid which uses the re-dubbed flashbacks and restores the footage deleted from the syndicated version... BUT deletes several instances of characters singing or lip-syncing to popular songs,presumably due to licensing issues.
