These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ear Worm: So I hope you solve this matter matter matter matter matter...
Ensemble Darkhorse: Carol Channing as the eccentric Muzzy Van Hossmere, who notably won a Golden Globe and Academy Award nomination as Best Supporting Actress.
Unfortunate Implications: Mrs Meers and the Chinese white slavery ring. The stage version tries to avoid this by having Mrs. Meers be an American actress who is unaware of how over the top and stereotypical she is, while the real Chinese characters are annoyed by it. Unfortunately, the "real" Chinese characters (Bun Foo and Ching Ho) are pretty stereotypical themselves, especially with the "Chinese" they speak.
