Celestia has had plenty of interesting drunken moments. That night with the mule, the time she woke up on pirate ship in the middle of the sea, and who could forget the time she woke up with a pair of wings, a horn, and a fancy tiara. Oh, and a hangover the size of the sun.
Warning: Drunken Silliness and plenty of foul mouthing
So me and Fuzzyfurvert were having a conversation about how it would be funny if we made a fic with a slightly similar idea to Conker's Bad Fur Day. It extended to Celestia being an earth pony who had one too many to drink. So you can blame him for this silliness.
