I feel that perhaps nopony has taken the time to explain this: Pinkie, your special abilities which allow you to, for example: enter a room despite all entrances being locked and warded; produce a baked good which requires an hour to produce in five minutes; or ride a slide in reverse; are abilities which most ponies either do not possess, or are not aware they possess. When a pony stares and asks a question you think to be obvious or strange, consider that it may, in fact, be  a case of you having done something which another pony (or otherwise) believes to be impossible.
