The Guinea Pig premiered on DISC CA on January 8, 2007. Have you ever wondered what it would be like to get punched in the head by a professional boxer? How about receiving the spiky brunt of a morning star blow? Well, it's probably a better idea not to try those things. Just leave it to the human Guinea Pig, Ryan Stock. Watch this guy communicate science by risking life and limb and being the subject of many dangerous experiments... again, don't try this... ever... If you're faint-of-heart, beware, Guinea Pig offers up a fresh perspective on the limits of the human body. While Ryan's feats will amaze you, they will also educate as the science behind the challenges is explained.
