To my faithful student, Twilight Sparkle,
Ah. I knew this day would come.
My dear, faithful Twilight Sparkle, I'm sad to say you have stumbled upon the H. Pokey conspiracy.
Fear not Twilight, I will recover your right hoof post haste. You are not the intended target of this operation.
... Seriously though Twilight, the context the 'hokey pokey' song refers to is limited strictly to the song itself referring to the dance and, moreover, the silliness inherent. Although if I did initiate a hokey pokey conspiracy, or had one initiated upon my directives and you were, in fact, not the intended target, you'd probably be receiving a very similar letter and a request not to publicize such. We'll discuss it over tea, because any hypothetical conspiracy of this nature would of course not be discussed over mail, even dragon-fire mail.
Your loving mentor,
Princess Celestia.PS. By royal decree I hereby return possession of one or all of your hooves to your person in perpetuity. Just in case.
