John Hodgman has an odd résumé. He’s not quite a stand-up comedian, though he will be performing comedy onstage Saturday at the Wilbur Theatre with his musical friend Jonathan Coulton. He has written three books of “facts” — “The Areas of My Expertise” (2005), “More Information Than You Require” (2008), and “That Is All” (2011) — but almost nothing in them is true. That particular brand of mastery landed him a job on “The Daily Show,” which is fake news. And though he is a devoted Mac user, he played the part of a PC in a series of TV commercials for Apple. At the Wilbur, the Brookline native will be presenting a show based on “That Is All,” including information about sports and wine, how to become a deranged millionaire, and the apocalypse that he, borrowing from Norse mythology, calls Ragnarok. The Globe caught up with him by phone as he was stuck in Seattle after Hurricane Sandy, trying to make it home to New York.
