Recently, Twilight Sparkle, the student of the renowned Princess Celestia, has obtained more than a pair of wings and the ranking of a princess, she's also obtained curiosity. More of it, at the least. Twilight wants to take some time out of her royal duties to study one of the recent dangers that has effected Equestria greatly.

Poison Joke.

Apparently, according to some books and Zecora, "if poison joke is left uncured, it will cause quite a stir" was not what one would think.
Twilight begins to get nervous when the affected Rarity begins to make clothing that has a little surprise weaved into its threads, and how Fluttershy's animals are turning a little more colorful than you'd expect. She then decides to study this funny flower bit by bit. Making the cure would save Equestria from eternal humiliation! And possibly, the halt of her wings becoming superglue sticky when she bites into a cupcake.

However, Poison Joke has some…unnerving effects that poor Twilight unfortunatly finds out as the plant begins to play games with her magic. As more pranks cause Ponyville to be the laughing stock, Twilight begins to wonder if its really the other ponies that are doing this. What if it's somepony else..?
What if..it was her?
