trolls
so the kids were playing dnd with some friends in the big room. it was kinda fun to eaves drop. a typical encounter went like this. you're going along and you're going along and you come to a bridge. when you try to cross the bridge a troll jumps up and says, if you want to cross my bridge you have to either fight me or sacrifice someone. at this point the gm's monologue is interrupted by the players nominating other players to be eaten by the troll. it gets kinda loud for a bit. when the volume dies down someone nominates a different player to be eaten by the troll. and the volume is renewed. this repeats until all players have been suggested at least once. they then decide to fight the troll. and win and collect their treasure. and the game continues. you're going along and you're going along and you come to a bridge...
