Throat of Steel Superhumans : Season 4 Episode 1

Stan's comic-book character's bodies had physically shocking features and gruesome modifications, enabling them to perform incredible feats. But Daniel Browning Smith goes in search of real people who claim their bodies can do things that no normal human can do. While most humans aren't able to withstand the effects of high voltage or current, Daniel investigates rumors of the legendary Duongs, an entire family in Vietnam that claim to be shock proof. John Doyle has a real-life ability to control his eyes like a chameleon that will literally make your eyes pop out in amazement. Thomas Blackthorne claims he can insert a jackhammer down his throat... and then turn it on. Stevie Star claims he can swallow shocking objects, and regurgitate them in any order he chooses. How he does it, it's hard to say, but it's impossible not to watch. Ryan Stock puts a meat hook through his skull and attempts to pull weights that will push human bone strength to the limit.
