Orlando Serrell claims he was turned into a real life genius after being hit on the head, and can remember the exact weather every day since the accident. Thanks to a unique genetic mutation, Joshua Carter is able to perform a staggering feat of contortion, that rewrites the limits of the human body. Kortney Olsen claims to have thighs even stronger than a python. Daniel tests her crush force, to see if she has turned her body into a human weapon.
