It was a lovely day in Ponyville. The birds were singing, the sun was shining, and yummy things were baking at Sugar Cube Corner!
And I, Pinkie Pie, have a nefarious plan! (insert evil cackle)
I shall get Discord back forall of those pranks he has pulled on me over the years! (insert another cackle)

As Pinkie was hopping down to Sugar Cube corner to spike some cookies and cakes with laxatives, Discord was also plotting. But, after all, he's the element of disharmony. He's always plotting. Always.

He started doing that thing where you start rubbing your hands(or paws, in his case) together, like you're trying to apply hand sanitizer. After he finished his plotting, he was walking to Sugar Cube Corner to find Pinkie. I mean, actually walking, for the first time in forever.(Don't you DARE start singing Frozen!)

At this point in time, our two sides of the story shall come together.
Pinkie and Discord spotted each other at the same time, Pinkie with spiked treats and sweets in hoof, and Discord, ready to summon something. Discord just made things easier,and teleported to her. They were standing two feet away from each other. Pinkie began to offer one of the sweets to Discord, and as soon as he began to lean forward to take one, Princess Twilight Sparkle teleported between them, from who-knows-where, looking rather insane. "AN APPLE A DAY KEEPS THE TROLLERS AWAY!", she shouted, as she exploded everywhere. Pinkie bent down, and licked the ground where the princess had exploded. "Mmmm!", she said,as she was licking it." Tastes like cake and sparkles!" Discord bent down to try it."So it does!", he said happily.

Soon, the whole town was on the ground, licking up what remains they could find. Even Celestia was down there!
And everyone lived crazily, ever, after!
