John Hodgman is everywhere. Over the past few years, he’s become comedy’s nerd laureate, a go-to for witty, esoteric humor that both mocks and indulges his cerebral tendencies. Via his role as a PC on those Mac commercials, his segment “You’re Welcome” on The Daily Show, and the snooty hyperliterate villain on the canceled HBO series Bored to Death, Hodgman has branched out, big time. Tonight, he comes to the Birchmere to promote That is All, the third and final entry in his Complete World Knowledge trilogy, the book series that helped establish him as America’s preeminent smarty-pants. With any luck, he’ll take on some impromptu cases as Judge John Hodgman, his persona on a podcast of the same name, in which he judges listeners’ squabbles. Perhaps this could be the year he makes the leap to TruTV.

John Hodgman performs with Paul & Storm at 7:30 p.m. at Birchmere, 3701 Mount Vernon Ave., Alexandria. $25. 703-549-7500.
