Note to self:
Eat that cake Friday! Or else Luna gets it...

Discord scratched his goat-beard-like goatee, eyeing the note attached to the small refrigerator.
"I knew sneaking in here was worth it." He smirked. "Celestia's private cake, in her own private fridge... I'd be stupid not to take it..."
He looked around to make sure that no one was looking.
"Whelp, finders keepers!"
"Discord?!" A terrifyingly familiar voice called out from behind him.
Crap

All Discord wanted was some cake. Sure, it belonged to Miss Sunbutt, but that just made it all the sweeter! It would have been nice if he hadn't been caught in the act though...
And neither one is willing to let it go.

(definitely not my best; didn't really put much effort into it. Just a sort of test-drive on FimFiction.)
