A little bit of minor inconsistency in TGMC:
During the "Happiness Hotel" song, Pops remarks "...Don't try to order dinner, there's no kitchen anymore...", and they can't order room service because "there's no food", according to Rizzo.
After Beauregarde drives them back to the Happiness Hotel in his taxi, following Kermit's initial meeting with Miss Piggy (whom he mistakes for Lady Holliday), he makes a U-turn in the lobby and goes through the kitchen, where the Swedish Chef brings out a pot of pasta with a steering wheel in it, and Pops says "Well, looks like steering wheel souffle for dinner." "Again?"
