Applejack drinks hard apple cider. Exactly NOTHING unexpected happens. Everything is fine, Ponyville is not destroyed, Discord and Chrysalis are not dancing around a fire while Celestia is hog-tied in a large cauldron of broth while Luna is playing dubstep in the background.
Nothing wrong happens here. Move along.
