In a special episode of the Discovery Channel adventure series "Man vs. Wild," Will Ferrell, teams up with survival expert Bear Grylls to hit the icy mountains of northern Sweden. Over the course of their 48 hours together, Grylls, an ex-Special Forces soldier, introduces Ferrell to the various ways of surviving in a glacier range. The duo rappel down a 100-foot frozen waterfall, make snowshoes from saplings and drink their own urine. "To be able to participate in an episode of 'Man vs. Wild' was a thrill of a lifetime," Ferrell said of the experience. "Even though I did get urine-drunk, which is sad."
