If you haven’t yet “come on down!” to check out Old School Game Show, what are you waiting for? A wacky take on TV game shows of yore—if Bob Barker was a Somervillian hipster with friends in bands—the show has enjoyed a semi-monthly residence at Oberon, among other locations, and had its biggest night yet at the Wilbur this February. Part interactive quiz show, part variety show, and all irreverent, wacked-out fun, the Ginny Nightshade-produced spectacular features a rotating crew of local musicians, stand-ups and other performers who take the stage between rounds of thematic and weird-as-hell trivia. Recent editions have included a category called “Baby Mama Drama,” for which audience members guessed famous, often disturbing, movie scenes as drawn by children. The price is wrong in all the right ways.
