We had a cat Barsik (terrible thief and shit). And so my mother decided to fry the chops.
Made minced meat, blinded chops and put into the frying pan fry (cat hanging around).
She turned away for a few seconds - turns and notices that the pan is left not engaged in space (both times with a steak - and before that it was not). I looked around and sees, sits the cat and not looking up faithfully looks in the eyes. So would she did not understand, only the cat somehow became somehow sway in the ass and later, in about 10 seconds with a wild shout ran out and the room. In the place where the cat sat - lay Burger.
This skunk not having to drag it away chose the only solution is to cover her ass.
