YMMV / My Little Pony: Friendship Is Magic S1 E15 "Feeling Pinkie Keen"
Accidental Aesop: Sort of. The reason for most of the controversy surrounding the episode is due to the Aesop being interpreted as "Don't try to figure out something you don't understand; you'll only look like an idiot" and "You should just accept what you're told and not try to test it." Some fans even took it to the point of the episode being a commentary on religion. Lauren Faust clarified the idea of the episode was meant to be "there are some things we may never understand or be able to prove, but that isn't a bad thing, mysteries like this are part of life and we just have to go with them". It should also be noted that Dave Polsky himself is an atheist who has said he believes everything is explainable by science.
