This is also the first episode that focuses on Ned Flanders.
This is the first of a very few episodes (excluding the non-canon "THOH's specials) showing Homer technically having an antagonistic role as he wishes The Leftorium to be a failure and go out of business, and then (initially) show no remorse for his actions, although he then does so.
The song 'Put On a Happy Face' from the musical Bye Bye Birdie appears twice. Sung by Maude, Rod and Todd Flanders in the car and later by everyone in the Leftorium when the place becomes a success.
The episode features cultural references to playwright William Shakespeare and the film It's a Wonderful Life. The title of the episode is a reference to the title of the poem "In Flanders Fields." Unusually, this episode had a large number of animation glitches, because the animation studio was training a new group of animators.
When Bart was wearing the shirt that said Maude loves Ned, it instead said Maude loves Nel.
