It's not new for weird things to be happening at Yellowstone. From earthquakes to rumors about the super-volcano about to erupt, Yellowstone always seems to have something going on. Add to that an increase in reports of UFO's over the park.
If you're not one of Russell Crowe's 825,000 followers on Twitter, maybe you should be. That way you can see a real-time play-by-play of how this whole UFO spotted outside of his office thing plays out.
We're already convinced that aliens exist, so it's not like we need any further proof. But these clips of identical UFOs hovering in the sky over Brooklyn and San Francisco blew us away. All hail our alien overlords! (The videos are a bit NSFW, by the way, due to some UFO-inspired potty mouth.)
