When I was at primary school, we would occasionally have steak and kidney pie (which I hated). The thing is I knew that a kidney was a part of your insides, and I didn't realise that other animals had them too. I had this image in my mind of two commandos walking around the school trying to find a child to kill for its kidneys the day before we had steak and kidney pie. I could never work out why nobody I knew ever got taken, though.
