Looks like Twilight Sparkle losing her mind is the most popular breakdown! I have to admit, Lesson Zero has been my favorite episode ever since it aired. Sonic Rainboom nukes, Fluttershy going wuju-style on a bear, and Rarity's overly dramatic attitude really showed off what this team is capable of when they go all out on a comedy style episode.
But I digress!
This is a little late, so we already have a poll up. Feel free to ask for new ones in the comments though, I'll find a fun one for after BroNYCon.
