I'm going to open this bag and put it in my belly

No grain is to ever be left unattended near Le Roy. I have witnessed many times this attempt to outsmart the human who created the grain bag.
In fact once at an old barn of ours where the fronts of the stalls were completely open, I turned my back to him to look at another horse when I heard the sound of a bag scraping against wood. I turn back to look at him and he had grabbed the open, half full bag with his teeth and was dragging it up the side of the stall while backing up. I didn't even say a word, he saw me looking at him and dropped it immediately. Then I got the "what are you lookin at?" look.
