The inquisitive grizzly wandered up to a family car as they drove through the national park in Montana, USA.
A video uploaded by the startled family shows the bear hopping up on its hind legs to peer inside the car, putting its paws on the windscreen to check out what they were doing.
Obviously, as grizzly bears can easily kill people, they didn't invite him in for a Teddy Bear's picnic.
After the family started the car engine, he wandered off to more exploring. And possibly catch up with Yogi Bear.
