This is one of the craziest things I've seen in awhile. I watched it full screen, and now I think I'm going to have nightmares.

I've never been to Winnett, Montana, and after watching this video I probably never will. Michael Delaney posted this video on his YouTube page. Not only did he film the rattlesnakes, he practically joined them in their den to get footage on his GoPro.

Things were going fine until one of the snakes struck his camera and knocked it down in the den. Skip ahead to the two-minute mark to see the rattlesnake strike the GoPro.
