I've talked about the Eaten Alive special that aired on the Discovery Channel last night quite a bit, and as it turns out, well, nobody as eaten alive.
Per the Discover Channel:
"Paul created this challenge to get maximum attention for one of the most beautiful and threatened parts of the world, the Amazon Rainforest and its wildlife. He went to great lengths to send this message and it was his absolute intention to be eaten alive. Ultimately, after the snake constricted Paul for over an hour and went for his head, the experiment had to be called when it became clear that Paul would be very seriously injured if he continued on. The safety of Paul, as well as the anaconda, was always our number-one priority."
Obviously they didn't shoot this live, so maybe they could have changed the title.
And then today, God bless Deadspin. They posted this list of the animals that would f%$k you up hand-to-hand combat. Anacondas come in ranked at #14.
The rest of the list is equally terrifying. I'd last maybe one minute combined vs. all of them.
