When a grizzly bear approaches a bus full of tourists it can be an exciting, tense occasion.
But when the approaching bear begins to roll playfully down a grassy hill, it seems, all tensions are eased and laughter erupts.
The accompanying footage was captured recently in Alaska’s Denali National Park, showing a bear acting rolling lazily down the slope and even pausing briefly to play dead.
It remains unclear whether the bruin was simply enjoying a carefree moment in the sun, or had recently discovered the magic berry bush.
But the Denali tourists were clearly amused, and David Pangborn's video was being shared widely since it was uploaded to YouTube on Sunday.
In less than 24 hours, it had garnered more than 138,000 views.
