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.

YMMV: As You Like It
Big Lipped Alligator Moment - The famous "all the world's a stage" speech (which actually has little to do with the meaning the quote is given) is a very morose speech delivered by the resident Eeyore and talks about the frailties of life and inevitability of death—very out of place in a sitcom-type comedy like As You Like It.
It happens at the end of the scene in which Jaques describes encountering Touchstone, who impresses him with a witty metaphor comparing... well, comparing a "sundial" (it's really his dick) to the way time works on humanity. He managed to make the process of first growing into yourself and then losing all that to the ravages of time hilarious, and thus inspires Jaques to try his hand at being a fool... except Jaques is reminded over the course of the scene of his current misfortunes (Duke Senior describes him as having been a "libertine" and mentions a few features that are consistent with the symptoms of syphilis) and so when he tries to copy Touchstone with a metaphor on the same topic, his observations are intelligent, but completely lacking in the humor that delighted him. So he makes himself sad again talking about how we're all going to die, and pretty much gives up on the idea of being a fool himself after that.
Orlando courts Rosalind while he thinks she's a man. Even in the productions that don't play this as him falling for "Ganymede,"note That name, by the by, originally belonged to Zeus' male lover in Greek Mythology and thus was used to denote an object of male homosexual affection in Renaissance England the implications are pretty overt.
Also a Les Yay: Rosalind and Celia.
And more Les Yay with Rosalind and Phoebe. Phoebe falls in Love at First Sight with Rosalind dressed as a man when Silvius is trying to get her to marry him.
Moe: Rosalind is arguably the most lovable character in all of Shakespeare.
Tsundere: Some productions have genderswapped Jaques. The resulting lines come off as intensely Tsundere toward everyone.
Where The Hell Is Springfield?: It's not altogether clear whether the Forest of Arden is, or rather, whether it's meant to be the one in Warwickshire close to Shakespeare's birthplace, or the Ardennes in France, where the story Rosalynde which inspired the play was set.
