- Deleted Scene: A scene was cut, but re-made into the DVD season pack where Professor Frink visits Homer's hospital room with a plan to create a shrinking submarine and plans to travel inside the Coma-ridden Homer by entering his rectum.
- What Could Have Been: FOX wanted four clip shows per season to add more to the episode count and for cheaper the cost. Writers and producers refused, fearing that would alienate fans. The next clip show (the one where Marge wants to talk to the family about romance) wouldn't be until season six.
