Here's a scary piece of video, posted to Vimeo by Wes Livingston. The clip wasn't posted with any explanatory text, but the video - and the comments in the video by the man doing the filming - are pretty self-explanatory.
With a camera attached to his head, the man releases a "baby moose" - a large moose calf - into the wild in Maine. Once the moose is untied and on her feet, however, she turns on the man and attacks. "First time I ever got beat up by a baby moose," the man says at one point. But it's pretty scary - she comes at him, hooves flying, knocks him to the ground and stomps on him. And it's all on this point-of-view clip that is ironically titled "Sweet Little Girl Moose":
"There's no call in being nasty!" the guy says to the moose. At least he keeps his sense of humor.
