"...and she just ate it in one gulp!" Pinkie was telling how Rainbow Dash had helped herself to Pinkie's personal cupcake stash. Discord was laughing and even Fluttershy, who was hosting their tea party, was giggling. "I mean, I love jalapeno-chocolate cupcakes with hot sauce frosting. Well, I like pretty much every cupcake but those are super duper yummy! Dashie didn't realize it until it was too late! I swear she had smoke coming out of her ears!" They laughed again, enjoying what Pinkie thought was one of the best pranks she pulled.
"Goodness, remind me not to eat any stray cupcakes you leave around, Pinkie," laughed Discord as he helped himself to another cookie. "Seriously, that's was quite a gamble. How did you know she would take one?"
"Oh, Rainbow Dash always grabs a cupcake. I tell her she should ask first, but she never listens. I never really mind, but sometimes I have experimental ones that the Cakes need tested and they don't want them tasted by anyone else until they're approved for sale." Pinkie swallowed the last of her tea and looked at Discord. "So, Mr. I-Can-Do-All-Sorts-Of-Crazy-Things, what was your favorite prank?"
Discord looked at Pinkie oddly. "How did you say all those hyphens?"
Fluttershy and Pinkie looked at him and asked, "What?"
"Uh, never mind. Greatest prank, eh? Well, that's easy. Did it just before the Two Best Sisters turned me into stone. I jinxed Tuesdays!"
Fluttershy and Pinkie looked at him and again asked, "WHAT?"
Fluttershy shook her disbelief first. "Are you saying you cursed an entire day? Why would you do that?"
"Why else, my dear Fluttershy? Tuesdays were boring." Fluttershy and Pinkie looked at each other, but before they could question him, he continued, "It's quite simple. Ponies and orange-striped cats don't like Mondays. The weekend is over. General discontentment and so on. Terrific for a spirit of Disharmony. I didn't need to touch that. I didn't touch weekends either because so much fun stuff happens. Fridays, ponies slack off their work thinking about what they'll do for the weekend. This cuts into the extra work they do on Thursdays because they were excited that the weekend was almost there."
As Discord sipped his tea cup, Fluttershy asked, "So that leaves Tuesday and Wednesday. Did you flip a bit to pick which day?"
"Oh, no. You see, Wednesdays are revered in Saddle Arabia. It's a reminder of the friendship or some such fluff that they share with the camels. I think they call it Hump Day. So, there was Tuesday, all left alone, nothing to make it stand out. So, I gave it a reason. I jinxed it so bad stuff would start on Tuesdays."
Pinkie and Fluttershy looked at each other. Fluttershy turned to Discord and asked, innocently enough, "But that sounds terrible!"
"Oh it was nothing major. Just harmless stuff. Like a pony might sit on a freshly painted bench or have too much pepper on their daisy sandwich. Funny enough, the first prank it started was quite the doozy. You'll never guess who the victim was." The girls just looked at each other, not sure if they would like the answer. "Me."
Fluttershy and Pinkie looked at him and yet again asked, "WHAT?!"
"Yes yes, the whole Elements of Harmony? Tia and Lulu found them on a Tuesday! I jinx it and it comes right back to get me!"
Pinkie scratched her head. "Sooooooooooooo the best prank you ever pulled was... on yourself?"
"Grand, isn't it? I never saw it coming!"
For a brief moment, they looked at each other, stunned. Then Pinkie started cracking a smile and giggling. Before they knew it, all three of them were laughing. After a while they calmed down and talked of other things. In the back of his mind, he thought of mentioning it to Twilight, but thought better of it. She'd probably try researching it to see how wide spread it was or something like that. Wouldn't want her to work herself into a frenzy.
