hitting a wolf with my own shoe, then wrestling the kidney the wolf just tore out of me from its mouth, beating the wolf to death with it, then throwing it at another wolf making its head explode, then dying of blood loss. not sure how the kidney happened, every other time its just been chunks that animals pull out like in the first post.
also, in one of the forts from the traps and attractions thread, reaching the lower level of a fort via a giant stairway, coming out in a massive room that went off in all directions, then being set upon from all angles by tentacle demons. in the fight one demon picked up a human lasher, pulled his lash off him, then hit him with it repeatedly before impaling him on one of its claws. that fight ended with me, unarmed on the ground crawling frantically away from the last demon, who had my last axe stuck in his shoulder. i found an arrow on the ground, turned and threw it at him, striking him in the face. this left him stunned long enough for me to stand up, pull my axe out and finish him. out of a party maxed out with companions only myself and an unconcious crossbowmen survived. that encouter is the height of awesomeness that i still compare all other game playing experiences to.
from fort mode - having my sherrif hit a recruits liver out with a steel hammer, damaging nothing else in his body. and then getting the "has taken joy in slaughter recently" and "has had a good sparring session recently" thoughts. having my multiple legendary mayor tantrom and kill half the platewearing legendary wrestler guards and several of her own pet cats. also, having a wrestler rip another wrestlers lung out.
and for just plain weird, having horses and cats and things grapple and break my limbs when they have been knocked over. not sure if that still happens, but the image of a small cat locking a humans arm in a wrestling hold then breaking it is demented.
