For visitors of Yellowstone National Park’s Bear World, a close encounter with wildlife is nothing unexpected. But these park-goers bit off a bit more than they could chew when they made a lengthy stop alongside this free-roaming grizzly bear.

Grizzlies are notoriously curious animals, known to inspect noises and objects to determine if they are edible ... or playable. Fun as the video may be to watch, we're pretty sure car-invading bears are a dangerous lot. They might live at tame-sounding Bear World, but they're still wild ... so it's probably best to treat them with caution and respect. Move along, and enjoy them from afar!
