LMAO! I never saw that movie: "Horrible Bosses", but I remember the episode, Hearth's Warming Eve. This fits perfectly with the clips of the movie that I noticed. (Chuckle) It makes total sense!
Rarity/Crown Princess Platinum is the snooty, pompous, wheedling stallion-eater! Pinkie Pie/Chancellor Puddinghead is the crazy, deluded, useless bureaucrat! Rainbow Dash is the cocky, self-absorbed, bullying douchebag! I can see why the assistants are so exasperated & tired ; glad they were the ones who came together & broke the curse that ended the era of hatred, prejudice & war that once divided the ponies.
Oh God, this looks awesome! Rainbow Dash is more than beautiful, I totally see her in that. i like you don't drew any hair! Fluttershy is so sweet, and Applejack - I don't want to start with applejack, I won't get done! Great work.
