Well, that happened.

It was a normal day in Canterlot.  Celestia had the sun brought up, the ponies in Cloudsdale had the sky clear of clouds (well, atleast in Canterlot, it was pouring in ponyville,) and a school from Manehattan was touring the Canterlot garden and was just coming up to the stone Discord.  Wait, stone Discord?  ARE YOU SERIOUS THEY DIDN'T THINK TO PUT HIM SOMEWHERE MORE SECURE AFTER THE LAST TIME A SCHOOL TOOK A FIELD TRIP TO THE GARDENS?!  Well, there teacher had asked what the 'statue' represented and the three ponies who thought they knew were Babs and the other two members of the Manehattan branch of the CMC.  As one would think they got in a fight about it.  It sounded so much like the one the original CMC had about discord that they probably just played that over the clip.  So then the teacher gave them the same assignment Cheerilee gave Scootaloo, Sweetie Belle, and Applebloom.  Then, surprise, surprise, discord escaped and went to cause chaos.
