What to do when chased by a bear? Well, bear spray could come in handy or you could simply just resist the stupid human gene and not get too close to mama bear and her cubs. That's the best answer.

However, not everyone abides by this nugget of wisdom.

And thanks to a Montana Fish and Wildlife and Parks employee the rest of us get a visual reminder of bear safety.

The bear vs. tourists footage was captured by Montana Fish, Wildlife & Parks photographer Winston Greely near the community of Gardiner, a Yellowstone gateway community.

"It serves as a reminder that wildlife can be unpredictable. For your safety and theirs, respect wildlife and give them room to roam," the agency wrote on its Facebook page. "View and photograph from established observation areas. Stay a safe distance to reduce stress on wildlife. Luckily, no one was hurt and these bears made it safely back to the forest."
