This is the best part of the film, The 5000 Fingers of Dr. T. See if you can spot any parallels between this song and the one I'm posting below from the Simpsons (episode One Dozen and One Greyhounds) sung by Mr. Burns! This film is a musical fantasy by Theodor Geisel (Dr. Seuss). He worked on the screenplay, script and wrote the musical lyrics (but did not like the end result one bit). This film was panned upon release but found a cult audience over the years. I'm guessing some Simpsons writers were among that audience. Film concerns young Bart Collins and his arch nemesis, Dr. T, the director/dictator of a musical academy/prison for boys. The T is for Terwilliger - that's Terwilliger, not Terwilliker as in Bart Simpson's arch-nemesis, but close!
They're both great fun, so enjoy!
