The chairperson selects an object/idea/whatever and announces whether it's animal, vegetable, mineral, and/or abstract. The others have to ask questions to figure out what it is. Whomever guesses the object correctly is given the chair for the next round; repeat ad nauseam.
[Snodgrass] No
Anything to do with supernatural things?
[Raak] No
Tuj
An ancient invention?
[Tuj] No, that would be a mineral, this is pure abstract
Anything to do with the passage of time?
[Inkspot] No

Would a clue help?
Is it mathematical?
[Dazed5] No
Tuj
Is it an emotion?
Nah, not mineral, I was thinking along Dazed5's lines!
Is it beauty?
Is it an experience of some sort?
[Tuj] No, sorry misunderstanding you
[Inkspot] No
[Raak] No
Hint: It's more of a concept than an idea
Would cavemen (women) have known this?
[Snodgrass] It's been a long time since I had contact with a caveperson. But I strongly suspect that they would.
Pain?
Hunger (perhaps)?
[Snodgrass] No
[Snodgrass II] No
Is this concept Gender Specific and if so is it Male orientated?
[Snodgrass] No, it's not gender specific. nor Male orientated.
Is it related to a particular time of the year?
Its very quiet in here. I think we're alone
[Snodgrass] No. It's busier than it was yesterday.
Do you want a clue?
Tuj
Is it the affirmative answer?
Hahaha!
Is it associated with one of the senses?
Yes please to a clue.
[Tuj] No, but very close
[Inkspot] No
Clue: Tuj was very close
Agreement?
[Raak] No, getting colder.
humour?
[Inkspot] NO
Nothing (as a concept)?
[Brendan] No.
Kim
Is it the negative answer?
[Kim] No? YES!

Let me rephrase that:
KIM WINS thank goodness for that.
Tuj
Blimey
And only after a stab in the dark. Mystifying!
[Tuj] It was quite a remarkable guess out of the blue, it's a pity you picked the wrong one.
Is it time to end this game? and replace it with something new?
That depends on whether Kim is likely to start a new round any time soon
Or is Kim playing the Reverse game where we start with Mornington Crescent and then ask how we arrived at that answer.
*shouts, screams, generally goes wild for Inkspot*

This is the end of the line. There is no more.
