Fellow Dwarfherders,
Sometimes I wonder whether "Dwarf" is just an euphemism for "Idiot". OK, they are good at making odd things like "..., a wharthog bone bed meanacing with spikes of dwarven sugar", but common sense is not really common among those fellas.
Take this Urist McIdiot as a prime example of dwarfiness: The refuse stockpile got a bit crowded, and the bone carver found nothing of interest any more to make bone crafts. So I built a Dwarven Atom Smasher right next to the pile, raised the bridge, placed the dump zone and had it filled. When they finished emptying out the pile, I called for a dwarf to pull the lever right next to the DAS. Urist came, pulled the lever, wondered "What am I going to do next?", and then moved on to whatever his dwarven brain thought was worthy of attention.
Well, you know that there is a delay between pulling the lever and the bridge going down? It was about as long as the dwarves' thought process. Guess where he went? Right across the garbage dump.
Big extra: That Urist McIdiot was one of my best axedwarves. He had a masterworks steel battle axe (Steel! In NoFluxLand!) and was wearing some masterworks armor pieces. To say that McSmith was p*ssed is a galactic understatement...
