The music world is sorely lacking in polka medleys these days, isn't it? Especially ones that give Britney Spears, Justin Bieber, Katy Perry and Ke$ha songs the tuba flourishes they so desperately need. Enter "Weird Al" Yankovic with his latest parody video. The legendary goofball, who's become the best-selling comedy recording artist in history (go ahead, look it up), does frighteningly atonal things to Lady Antebellum's "Need You Now" and advertises his first TV special in more than a decade. The clip also flushes Flo Rida down the toilet and creates a giant pole-dancing Brit-bot. All to a crazy accordion beat! (It's animated, so it's OK.) The idea probably sprang from Lady Gaga's hit "Poker Face," which became "Polka Face" after Al was finished with it. From there, why not keep going? Jamie Foxx and Pink can take a joke. "Weird Al" Yankovic Live!—The Apocalypse Tour airs Saturday night on Comedy Central.
