Bigfoot Family Of Four Filmed In Yellowstone National Park

He’s the big hairy fellow we all desperately want to believe in.

So it’s with great relief we bring you this definitive proof of the existence of Bigfoot.

Footage of a family of four of the beasts strolling through the snowy foothills of Yellowstone National Park has gone viral.

The clip, apparently taken from the park’s own Old Faithful Geyser Streaming webcam, shows the foursome in the background of a bucolic scene of grazing bison.

The user asks: “Would you risk death by buffalo to pull off a Bigfoot hoax?”
