In a video that proves, among other things, that terror can be universally understood by all, no matter what language in which it's expressed, this group of Brazilians in a small boat spot a massive anaconda. As the woman on the boat proceeds to loudly voice her discomfort with the situation, a man on board pursues the yellow anaconda and grabs it by the tail, presumably so it can be better seen on the video they are shooting. (If I'm not mistaken, at 1:54 I think the woman tells him he's sick in the head.) What an amazing sight! Via Geekologie.
Such things actually exist. *shudder*
