TRIVIA—For the past four years, local podcasters Bobby Roberts and Cort Webber have been hosting the super popular Geek Trivia—handing out thousands of dollars of prizes and comic book-related swag to those who know the difference between Boba Fett and Bib Fortuna. Tonight is the final Geek Trivia ever… so grab some friends, order some beers, and give winning this thing one last shot. ERIK HENRIKSEN

MUSIC—It’s not actually spelled out anywhere, but Billy Idol’s website STRONGLY suggests the 58-year-old still performs shirtless—at least on occasion. Sure, tonight’s show is putatively sold out, but do you really want to risk missing all that glistening, screaming flesh just because dealing with scalpers is a bummer? No one ever said the cradle of love rocked easy, people. DIRK VANDERHART
