Bloody Hell! It's hard enough when you are in the seat to attempt to answer questions in a manner which does not mislead without having each move analysed when the game is over.
Whilst I must admit the discussion has been most entertaining, Kayl, you have my sympathy. Regardless, carry on the discussion - assuming that Boolbar doesn't produce the gavel; as I said 'tis amusing to follow the arguments of logic. ... ;-)

Mainly, I would hope that none of us would choose "the contents of a vegetarian's colon" for a topic. But, yes, I would probably call the vegetarian's waste 'vegetable' and the meat-eater's 'animal and vegetable' (since the meat-eater presumably doesn't live solely on meat... although, another animal -- a cheetah, say...)

I really shouldn't have brought this up, should I?

[Riff] I hope you're not bringing it up, or you'd be suffering from major digestive malfunction!

[Riff] Rotter! "The content of a vegetarian's colon" was exactly the topic I was going to choose if I got into the chair. I would have set it as abstract since its animal, vegetable or mineral content could not be ascertained without removing it from the colon in question.

I do love sparking linguistic controversy.

Blimey! I thought that was a question leading towards the correct answer, not the answer itself. OK, I'll try and pick something simple that shouldn't lead to confusion (ha!) and get someone else in the chair. VEGETABLE

[Kim] I do apologise. Let me offer you, as a replacement, my backup idea: a chocolate-covered billiard ball. No one'll ever guess that.

Oops!
