You may or may not know this, but Conan O'Brien initially worked as a writer for the early (read: best) seasons of The Simpsons.

One of Conan O'Brien's episodes included the episode 'Homer Vs. The Monorail' and an infamous musical number by Lyle Langley, the monorail baron who sold the idea to Springfield.

Voiced by Phil Hartmann, the comedic genius who sadly passed away several years ago, the song is a pop-culture classic and in his stead, Conan O'Brien stepped into sing his piece.

The live show, Simpsons Take The Bowl, is currently playing at the Hollywood Bowl in Los Angeles and features cast members Hank Azaria and a few others turning up in their roles.
