Three-Year-Old Marek Sings LMFAO's 'Sexy And I Know It' (VIDEO)

Between "Party Rock Anthem" and "Sexy and I Know It," it's safe to say that LMFAO had a pretty good year on the Top 40 charts, but their success doesn't just stop with radio play and mp3 downloads.

Three-year-old Marek has heard the song and seen their music video so many times that he actually knows most of the words and can emulate some of the goofy dance moves. For some reason hearing "in a Speedo trying to tan my cheeks" come out of a child's mouth is a little more charming than hearing it from an adult.

Watch him bust out his moves in the family kitchen and you'll totally see what we mean.
