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: Ponies The Anthology
Hilarious in Hindsight: The Animaniacs sequences in II were funny to begin with, but were made even more fitting with The Hub's acquisition of the aforementioned series.
Additionally, the first of them is "Boingy Boingy Boingy" set to Apple Bloom bouncing on a jumping Big Macintosh. Pinkie Pie would actually recite that line in "Games Ponies Play".
