[BM] If it is alive/dead but the components thereof have not sufficiently decomposed to the point where it would be considered a mineral by geological standards, then it's animal and/or vegetable. A cricket ball, e.g. is both animal and vegetable. Bone, if that were the object in question, I would list as animal and mineral.
Or they just found the idea of Darren and Derren on stage at the same time to be too disturbing...
[BM] All sounds a bit quantum, to me. What you're trying to do is draw definite lines along fuzzy boundaries, which looks OK from a distance but when you look closely, well, aren't.
We had the same argument over SARS when that was a subject -- was it an animal, vegetable, or mineral? A virus is a non-cellular collection of ribonucleic acids which merely attaches to an unlucky living cell and sort-of-passively uses the cell's contents to propagate itself.
I'd claim it's a mineral, but others would have a valid argument otherwise.
I'm staggered they're showing Russian Roulette on TV. There was enough trouble with Jackass!! What the f*ck is going on? In a way, I hope he cops it. Would teach the lads at Channel 4 a lesson, eh? Mwahahaah!
The trouble with all these illusionists doing "high-risk" stunts is that we all *know* they'll survive it. It's like an adventure movie, you always have the nauseating knowledge the protagonist will come through in the end. Of course, there have been the rare occasions where it's all gone horribly wrong, but frankly I much prefer smaller, close-up magic than the hyped-up stuff.
