The strangest thing you've ever seen on an x-ray?

I've also seen some interesting things on vet X-ray. I had a golden retriever who, over the years, ate a watch, contact lenses, glasses, a coke can, railroad spike, tin soldiers, paring knife and my mother's antique doll. The vet used to do an X-ray every time I brought the dog in for shots, whatever, "just to see what's in there NOW." The paring knife was still there when the dog died at the ripe old age of 13, about 7 years after she ate it! (Must have been a very dull knife!)

Ahh, here come the foreign-object-in-rectum stories

I know it is just a TV show, but I have never laughed so hard as that episode of Scrubs when the guy had the light bulb up his rear and when looking at the x-ray, Dr. Cox says "either that or his colon has a great idea"
