It really is a fantastic episode.

In the early ’90s, before Conan O’Brien was Conan O’Brien, he was a staff writer for “The Simpsons”. While there, he led the creation of one of the greatest episodes of all time, “Marge vs. the Monorail”. Three decades later, friend-of-the-site Oliver Y. tipped me off to the Ringer’s excellent look at how the episode came to be.
