The Indonesian military ate snakes, headbutted bricks, and walked through fire for James Mattis

That was a pretty neat demonstration. As a PVT at Hunter Liggett our Mess SGT cooked a Rattle Snake for us while we were in the field, fried in butter with onions and peppers. It was pretty decent.
Don't know as I'd care for raw snake or the blood thing but in a survival situation I could see it doing in a pinch.
