This little mistake is located in the scene where Gracie tells her pageant trainer guy that she has no talent prepared. He goes up to the cop guy, and they start to argue. If you watch Gracie in the background, you'll notice she walks up to the donut plate, looks around, then shoves two donuts into her bra. You can clearly see that this is the only place she puts the donuts. She then walks up behind the two of them (the camara never cuts away, so you see the whole ordeal) and says something. She then proceeds to walk away, but not before her trainer makes her give up the goods. As she's leaving, a police dog starts sniffing at her and she produces another donut from under her dress, between her legs. It's pretty obvious if you watch that she never put the donut under there in the first place.
