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: Jersey Boys
Ear Worm: Lots of the Four Seasons' songs, but "Sherry" and "Walk Like a Man" are notable.
What Do You Mean, It's Not for Kids?: You'd think this would be a wholesome, family-friendly show, considering how wholesome and family-friendly the music of the Four Seasons (and Frankie Valli) is. Then the curtain rises, and the show unfurls — full of profanities, double entendres, and very adult situations. This is why there's always a big sign posted in the lobbies of theaters showing Jersey Boys warning parents of the adult content present in the musical. For example, kids may ask their parents, "What's a blowjob?"
