My ex girlfriends father is a gastro endosurgeon (think thats whats its called).
The weird things they have removede from people, champagne glasses, 20mm dummy shells, carrots, cell phones. Well, anyways, people have funny excuses, "well, i was in the shower and had some drink, and i accidentally sat down on the glass, and up it went."
He even gave me some advice, should i ever encounter a situation like this. If its a bottle, and the opening is out, you can pour plaster in there and insert some kind of handle into it, like a cork screw, then yank it out when it has hardened.
