DVD Easter Egg: Season 9, Disc 3. When Lisa holds up the puzzle on the back of her lunch (near the beginning of the episode), press the number 6 on your DVD remote to unlock a full episode length commentary from Bill Oakley and Josh Weinstein. They discuss their time spent working on the show, and address a few important issues.
Susie Dietter, one of the directors of the show, also left the show after this episode, but returned for Yokel Chords (2007).
The name of the episode was the center of an argument that Bill Oakley and Ned Goldreyer had, as Oakley had originally wanted to have the episode named "Lisa the Simpson", although Goldreyer wanted to name it "Suddenly Stupid", a pun on Suddenly Susan (1996).
All of the male Simpson family members that showed up were voiced by Dan Castellaneta. He had asked for the recording tape to be run for about twenty minutes, so he could do many different voice variations that would fit the different men, but still be close to Homer's voice.
