A popular online video shows two baby bears playing in the road at Yosemite

And this, folks, is why you should always drive slowly through National Parks.

This video of two baby bears playing in the roadway was initially posted to YouTube back in 2011. It’s experiencing a surge in popularity this week, and it’s easy to see why: Those bears – “puppy-sized,” as one onlooker declares them – are darn cute.

The bears were spotted in a drive through California’s Yosemite National Park, and traffic literally stopped until they finished doing their thing. That thing, of course, was playfully tussling with each other, without much regard to the humans watching them.

The video ends with the bears joining up with their mother and scampering away into the brush, surely to go spread cuteness elsewhere.
