- Actor Allusion: When Marge tries to convince Sting to take a break from digging Bart out, Homer stops her claiming he's a good digger. Sting actually worked as a ditch digger before his music career took off.
- What Could Have Been:
- The scene of Homer getting tricked by Bart into thinking aliens have invaded was originally supposed to have Homer mix a bowl of poisoned Kool-Aid for his family to drink. The idea was scrapped after the writers found the joke too dark and the censors complained that it would lead to copycat incidents, so instead, they have Homer grab a shotgun and run for the door.
- Bruce Springsteen was originally going to guest star in the role that went to Sting.
- During the part where Homer tries to show Bart that the microphone he got him for his birthday is worth playing with, Homer was originally supposed to sing The Wreck of the Edmund Fitzgerald instead of Convoy, but Gordon Lightfoot (the singer of The Wreck of the Edmund Fitzgerald) would only allow the song to be used if the producers got permission from the families of the twenty-nine crewmen who died on the ship (since the song is based on a real event). The producers found it to be too much work, so they scrapped it.
