YMMV: MLP: Friendship Is Magic S1 E20 "Green Isn't Your Color"
YMMV examples here:
- Accidental Innuendo: Rarity: "I'm the one who should be mobbed by strangers wherever I go!"
- Ensemble Darkhorse: Photo Finish seems to be quite popular in the fandom.
- The Scrappy: Pinkie Pie is this for the episode, due to her constant popping up to keep Twilight from confessing on what Fluttershy and Rarity think about each other, which would have solved the episode's problems. And even at the very end, after Rarity and Fluttershy tell the truth to each other, she's off the hook on their secrets, but blurts out the "Spike loves Rarity" secret...despite the fact that everypony knows about it, and Pinkie's disappointed at that.
- Squick: Fluttershy's magically forced nose-picking scene in the second fashion show. The ponies (even Derpy) in the audiences were really displeased.
