Alternate Setup:



Rainbow Dash: It must be really hard for Pinkie Pie to not throw a party.



Twilight Sparkle: If you think it's difficult for Pinkie to suppress basic urges, you shoud see Princess Celestia when it comes to desserts.



(Meanwhile, in Canterlot)



Celestia: (staring at a plate full of cakes) Cake is a sometimes food. Cake is a sometimes food. Cake is a sometimes food. (beat) NOW is sometimes! (Om Nom Nom!)
