I embarked on a possibly sightly crack brained plumbing project.
Close to ground level I have a brook fed cistern. Far below ground level I'm building a new cistern/well near the new hospital. I decide to dig a tunnel from Cistern 2 to Cistern 1.
I get ready to breech the bottom of the #1 and realize I don't have much of an exit strategy.
I'm going to have a dwarf in a long tunnel that will rapidly be filling with water. And he might not get back behind the floodgate in time.
So instead of one of my good miners I find the sorriest dope in the base, hand him a pick and boot him into the tunnel. I figure if things go wrong retrieving a body is easier than re-engineering the whole thing.
So the palooka hits the last stone and, it's not a flow, it's like a geyser. He disapears, and the water slams into the first bend 15 squares behind him. I pause and inspect. He's STANDING there LIKE A BOSS. He then swims UPSTREAM, and up about 8 Z levels of water, climbs out of Cistern 1 and hurries off. BECAUSE he's late for archery practice. I want to make this guy Mayor now.
Then I look at the restof the tunnel. And halfway down it I find, a wheelbarrow. a dead dwarf, and his dead pet dog. I think he was after some stones. He died over diorite, and not just diorite, a random piece of unusually inaccessible diorite...instead of you know, gettting one of the ones that are EVERYWHERE ELSE.
*facepalm*
