In Canterlot's central shopping district, gift clocks are the newest Hearth’s Warming sensation: a present every day until the Eve itself, all in one convenient giant box! You can give them to other ponies! You can buy them for yourself and get a little surprise with every sunrise! They come in all sorts of themes! And as our eagerly shopping Bearers are about to discover, every last one has something in common.
Really, why does everypony keep presuming the ensuing riots are their fault?
