(or perhaps under the category of NPCs with brainpower equivalent Homer Simpson)I thought it was weird that when standing next to the windmill, you can get messages like "Buzzard takes 6 crush damage" I figured the birds flying around were just window dressing, not really "in the game".
But then later on, it was even funnier when miles away I repeatedly got messages that the NPC in that area was taking crush damage ... apparently standing a bit too close to the windmill. I guess if I was closer, I may have actually heard the "Doh! Doh! Doh!"
