Before he became Dunder Mifflin’s resident slacker on The Office, B.J. Novak was refining his future character by pulling pranks on Boston’s Museum of Fine Arts. During a trip to the institution’s popular 1997 exhibit, Tales from the Land of Dragons, the actor flexed his funny bone when he and a group of friends decided to re-record the audio guide for the show. Novak’s pal with an Eastern European accent (calling himself Lev Davidovich Bronstein) narrated the newly dubbed tour, and the friends swapped tapes after buying their tickets and renting the audio tour equipment. The actor was only in high school at the time, and recently told his alma mater about the prank revealing what was said. “The first three minutes of the tape were completely accurate … but about 3 minutes in, the tour started getting a little weird. The guy started injecting his personal opinions. He’d say, ‘Personally I think this painting is a piece of crap,'” Novak told audiences. Apparently the pranksters also encouraged listeners to do the hokey pokey and inhale the paint fumes. Sound about right for Ryan Howard?
