One of the first things you learn when going camping is not to get between a mother bear and her cub. Mother bears are notoriously defensive, and they'll do anything to protect their children.
In this instance, then, the garage door made a huge mistake.
In the video, a mother angrily looks on while her cub auditions for cirque du soleil. I'm not sure which feat of strength is more impressive -- the cub's high-wire act or the mother single-handedly opening the garage door.
The hero of that video? The ladder. We could've been headed toward a tragic ending if the cub had to find another way down.
