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.
YMMV: The Barber Of Seville
The original opera:
Adaptation Displacement: as previously mentioned, Rossini's opera has triumphed over not only three competitors in the same genre, but the original play.
Ear Worm: Say it with me now: Figaro! Figaro, Figaro Figaro...
Memetic Mutation: The rapid-fire "Figaro, figaro, figaro figarofigarofigaro" part of "Figaro's Aria" has been parodied in more works than could probably be counted.
Nightmare Fuel: Admit it — when Woody s-l-o-w-l-y opened his razor ("colla donneeee-e-e-e-etta"), you gave a kind of shudder, didn't you?
Values Dissonance: The Native American customer, who, of course, wears a headdress and carries a tomahawk, in the 1940s — and is made into a cigar-store Indian.
