Speaking of which, my mother was once a doctor and told me of a patient who came in complaining of stomach pains. An X-Ray showed two rings inside him. Very mysterious. Once extracted, it turned out that he had an empty tube of Ajax up him. Apparently he forgot that he had put it there, or was just too embarassed to say so. This wouldn't be so entirely farfetched had he not come back a month later, but this time the foreign object in question was a rolled-up newspaper. Some people just don't learn.
