As I mentioned in another thread, I had a GC stuck once. It stopped him from restoring the crops, etc., but unfortunately not from calling parties.

I think the funniest thing I've seen is how villagers will just walk through each other as if they are ghosts. Maybe in VV2, they will learn to yield the right of way to the older villager.

I've also seen several villagers "relaxing" yet lugging a big rock around.
