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 Polski himself is an atheist who has said he believes everything is explainable by science.
Some fans also objected to the moral because they thought it presented an anti-intellectualist viewpoint. ("It's wrong to attempt to understand things. Just accept them at face value.") Lauren Faust was quick to apologize for this, saying she would never want to give kids that kind of message.
This episode is a Guilty Pleasure for some in light of the humor that's showcased throughout.
Lost Aesop: In a rather different sense. According to Word of God, the moral was supposed to be something like "something can be true even though you don't understand it, and that's okay", but needless to say, a great deal of the fandom didn't see that message as being very clear.
