That's it. What else can I possibly say here?
This video from Vanessa Renwick uses vintage footage—back before the ASPCA shunned such practices—of a horse kicking the furry ass of a bear. Not sure how this accurately portrays Quasi's "Little White Horse," but then again it's a video where a bear and a horse fight each other. The bear jumps on the horse's back and rides it!
It's probably best not to overthink these things.
