In the middle of my friend's playthrough they were direly over encumbered, and trying to get up a hill. They had put a lot of their belongings in a crate, and had been pushing the crate inch by inch up this mountain road. Their eyes were drawn from the prize (a mound of loot-filled corpses at the top of the road), and as I warned them about moving too far, the box's physics slipped off the model and it slowly skidded back down the road to cries of anguish. That is the most I have ever enjoyed anything Bethesda ever made.
