“Weird Al” Yankovic sitting down for Stephen Colbert’s rapid-fire Questionert is one of those pairings that writes itself, and the execution delivers fully. Over several minutes, Yankovic fields questions covering his favorite action movie, the five words he’d use to describe the rest of his life, unconventional sandwich preferences, and nostalgic moments from a career that now spans decades of musical parody at the highest level. Yankovic has always been a more interesting interview subject than people expect, precise and thoughtful underneath the absurdist surface, and the Questionert format is perfectly calibrated to let both qualities show up simultaneously. For anyone who grew up with “Eat It,” “Amish Paradise,” or “White & Nerdy,” this one lands.
