Sources say that he does, or will rather on Discovery Channel's "Man vs Wild".  Ferrell is set to guest star with Bear Grylls in a show that will "air in early June".  The episode is "in the far north of Sweden" and the two will be "rappelling down hundred-foot frozen waterfalls, tandem abseiling off a helicopter and staying warm overnight in sub-zero temperatures."

On doing the gig Ferrell said it was " a thrill of a lifetime, even though I did get urine-drunk, which is sad."
