Math?! I thought this was a school of friendship!





Seriously, what an episode. It was hilarious, but you're right, Discord was being a total jerk. I know it's part of his charm, but you'd think he wouldn't be quite this petty anymore. Oh well, at least maybe now the ponies will FINALLY stop leaving him out of the important things in their lives. He never takes that well, and they really should know that by now.
