In that game, I micromanaged it quite a lot because tormenting the nobles was the
sole purpose of that fort.
I was also keeping a close eye on the refuse piles, so that dead vermin (and anything else that wouldn't produce bones or shell) could be thrown in quickly. I love the idea of my dwarves pelting the nobility with thrown dead rats and things, while they can do nothing but rage and fight amongst themselves.
IIRC, the philosopher went stark raving mad first, then the count consort went berzerk and attacked the king (he was an adamantium king), but was struck down, then the tax collector went stark raving mad too (I like to think he was babbling about being unable to collect taxes for so long), then the countess went melancholy (yet didn't drown herself in the filthy water supply, possibly because the only accessible tile of water was a downwards ramp), then the king died of dehydration due to his wounds. All of them but the hammerer were almost
constantly tantrumming, near the end. Also, the philosopher went insane without ever throwing a tantrum.
Next time I should try to become the mountainhome and do the same thing. The more nobles in the lockup, the better. Ooh, I could try collecting as many widow/er consorts as possible, too!
I should also see if it's possible to Pit captured live vermin.
This is all pretty much on the original topic, too.
These are the sorts of goals that DF players set for themselves, once they can make a stable fortress about... uh... half the time, in my case.
