Weeks At No. 1: 2
Producer: Party Rock

"Sexy and I Know It" is kind of like cough syrup: do not operate heavy machinery under its influence. It was the song you hated to love, but with a too-easy-to-follow lead up to the chorus and beat-drop, it was hard not to dance to it. The music video was essentially a dance tutorial, in which you could mimic the obnoxious moves of SkyBlu, Redfoo, or the beloved Shuffle Bot.
