Pinkie Pie can REALLY throw a party, and the aftermath is usually pretty good, except for that one time...
Twilight is unconscious, Applejack is looking through porno mags, Pinkie Pie is, well, Pinkie Pie, Rainbow Dash has "slightly" overdosed, Shining Armor may or may not become an alicorn, Luna is NOT a virgin, and Celestia just has a headache from all these goddam letters!
