So after 500+, maybe 800+, hours playing Skyrim, while searching the hills of the Rift for Scaly Pholiota with my alchemist, I just ran into a novice necromancer and his four undead chickens on a hilltop southeast of Ivarstead. I laughed out loud for a good ten minutes. I love this game for the utter randomness to be found while exploring.
