The F-bomb never sounded so charming, and never before had the word wrestled its way into Grammy Awards territory (the song landed five nominations). Family audiences went gaga over the song's radio-friendly counterpart, "Forget You," thanks in part to its exposure on Fox's "Glee." Bruno Mars's Smeezingtons crew helped pen the dirty-word ditty. How did such a lewd title win so much love? "It's cute as a button," Green told Rolling Stone. "It's very disarming, and it actually sounds nothing like that title—it's got a very tongue-in-cheek quality. It's "Fuck You"—but with a smile on your face."
