If you quick travel to Joseph Seed's sanctuary, then walk back south along the west (right) side of the river, you can discover a spot on a rock with a cliff to your right where, if you throw bait ahead of you, animals will throw themselves off the cliff to land in front of you most times. They either fall to their deaths, or lie unconscious for a moment, then leap several feet into the air.
It's a useful way to acquire skins - wolf, bear and cougar - for just the cost of bait. Plus, it's funny as hell.
