  • This is the final Simpsons episode show ran by Bill Oakley and Josh Weinstein. It was a production Season 8 episode held over until late Season 9.


  • The episode was originally going to be titled "Suddenly Stupid", a parody of the 1996 NBC series "Suddenly Susan" that aired after "Seinfeld". It was decided against using that parody title and instead used the template of "(Simpsons Family Member) The..." such "Bart the Daredevil" and "Homer the Heretic".
