What Mebzuth has in creativity and meta-humour, he lacks in brains. Dude decided to smooth a wall fom the outside of a fortress (which somehow would also smooth the wall on the inside), during a goblin seige. My squad that I had been training for months in-game were already wiped out, so I had to assemble a crew of dwarves with no combat training at all just to save his sorry ass.
As luck would have it, as soon as he realized what a poor choice he had made, he ran off away from the fortress he had just exited, but only one goblin pursued him. He was chased across the map, finally fighting back out of desperation and fracturing the goblin's leg. So the goblin gave up and Mebzuth wandered off... just before getting attacked by an entire different squad of goblins.
He was almost certain to be killed this time, so I assigned him to a burrow inside the fortress, hoping he'd get it through his dwarven skull that he might want to go to the one place where the goblins couln't follow him. He seemed to be going for that, but, luckily enough aforementioned the aforementioned last resort squad replacements managed to kill just enough of the other goblin squad for the goblins to call the seige off.
And that's how my Too Dumb To Live but too important to die Engraver got about 10 people killed just because he likes working outdoors.
EDIT: He's dead. Apparently a couple goblins stay behind and one of them caught him. It's a painful irony that he'll be buried in a tomb full of ameteur engravings. Perhaps I just won't engrave it at all.
