This guy and his wife have this big huge dog. It's a rare breed, about the size of a Newfoundland, and gentle and friendly. Also very hungry. So, when the guy came home the other day and glanced into the kitchen and saw the dog chewing on a bone in the shadows, he thought nothing of it and kept on his way--figured his wife had gotten the dog a bone. He came back into the kitchen a while later, flicked on the lights, and found that his dog was happily sitting in the middle of a sea of human bones, strewn across the kitchen floor.
His wife is a medical student, see, and she happens to have a box of bones for study purposes. The dog, it seems, got into them. Funny, undoubtedly; but ghoulish too.
So remember this when you donate your body to science. Your bones may end up in a box in some med student's house, where a dog might scatter them on the kitchen floor and chew upon them. Hey, it's nature; what can you do?
