You ever seen a pissed off grizzly ram its head into the steel door of a vintage car from the 1950s? Well, you’re about to.

The video below was taken in 1959 by John and Frank Craighead. The brothers were conducting research on the dwindling grizzly bear population in Yellowstone National Park.

They attempted to tag the sedated bear, but things clearly didn’t go according to plan. The angry bear wakes up and starts charging after the brothers and their fellow researchers. Mental.

The National Parks Service estimated that there were only 136 grizzlies living in Yellowstone by 1975. That population has bounced back significantly with the estimated total bear population in Yellowstone being 728 bears in 2019.

I’m glad things were done to protect these bears and allow for their population to rebound, but I’m probably even more scared of them after watching that video above.

That bear went full-blown psycho rage-killer on that car. Yikes.
