LMFAO has staying power (laugh now)! Seriously, with videos like “Sexy and I know It,”the group is proving that they just may be more than a novelty act. If nothing else, they definitely have figured out the formula for keeping their audience blushing. Not sure if the uncle and nephew team will ever be able to live down dancing around in their tighty whities, but their gyrating moves definitely made for an “interesting” video. It has to be pretty cool to have bragging rights about dancing in your undies with p*rn legend Ron Jeremy.
