Should you encounter a large bison while strolling the paths of Yellowstone National Park, do keep in mind Elmer Fudd's timeless advice and "be vewy, vewy quiet."
This particular necessity is perfectly demonstrated in the video above from Michael Berman, who posted a seriously close encounter online. Watch until the end to see the priceless looks on their faces, and remember that a bison always has the right-of-way.
CORRECTION: A previous version of this article credited Berman with shooting the video. He merely posted it online.
