That's nothing. An acquaintance of mine who was an emergency room told of a patient who used to be brought in on a regular basis to have Barbie doll heads removed from his stomach. Apparently, he had a ritual in which he would shave their heads, chop 'em off, swallow them and then wank as he was shitting them out ... and sometimes things didn't go according to plan.
Of course, it did occur to me this might be another urban myth (a la gerbil stuffing), but I never could find out for sure one way or the other...
