Viral Video Of The Day: "Angry Bison Attacks in Yellowstone"

Here's something you don't see everyday!

What these teenagers planned on was beautiful day at Yellowstone National Park. What they didn't expect was to come face to face with a big angry bison.

This video was posted by YouTube user MrFuLei who writes "this shocking video appears to show a man encouraging a group of kids to make friends with a bison at Yellowstone National Park, as he holds back at a safe distance."

Now I don't know about you, but if that guy was staring me down, I wouldn't stand around waiting to find out what it wanted.

As for the person behind the camera urging the teens to touch the bison, probably not the best idea. Fortunately for these kids they managed to escape the rampage.
