Jokes on you!

Ever since she woke, Pinkie Pie knew that a god-class prankster was about. And she had no doubts that she'd be pranked too.

Pinkie was ever vigilant as she searched for any hidden pranks. In her closet, her party cannon, Gummy, Mr. and Mrs. Cake (Much to their displeasure) and even the baby Cakes.

We she felt certain that she wouldn't be pranked, she made her way to the cash register to begin work for the day.

The first couple of hours were decent, only two ponies entered. Then she noticed a certain couple heading up to the register.

"Starlight? Sunburst?" She asked incredulously, "You two are dating now?!"

"Maybe?" Starlight managed to say.

After pushing her jaw back up, Pinkie shook her head, "Well then, what do you two want?"

"W-well, can we just have a couple of milkshakes to talk over?" Sunburst suggested.

"No problemo!" Pinkie answered merrily, "But, I have to warn you two that a grade A prankster is about. . ."

"We know Pinkie." Both Sunburst and Starlight said.

So, Pinkie showed them to a table with a great view of Ponyville before heading into the kitchens to start the milkshakes.

This, is where everything went wrong.

First, when Pinkie went to get the vanilla ice cream, she got her mane stuck to the freezer. How even?

Then, she opened the fridge to get the milk. After she finished adding the milk, she noticed that the milk she grabbed was Mrs. Cake's milk for the babies.

Gasping in fear, Pinkie had to down the shakes. Which tasted surprisingly sweet.

Then, finally, after making two new shakes, she placed them on a tray. Which just fell in half.

Pinkie was starting to get furious. The prankster was good, switching the milk around, sawing her tray, and somehow sticking her mane to the freezer. But she would triumph.

25 wasted shakes later, the kitchen was coated in a layer of milk, Pinkie had flour all over her, the eggs she took out to bake a cake were all live chicks. And the cherry on top was that she had found a picture of her and Dash that she had once hidden from public eyes, as it showed a more 'Adult' Pinkie.

So, covered in kitchen ingriedients and clutching the picture for all to see, she gave Starlight and Sunburst their shakes before heading back inside the kitchen to begin cleaning up.
