I empathize with this video as I too, am literally no good at math, piano, or martial arts. I do however, like to pretend that I kick major butt with kung fu, in the privacy of my own bathroom mirror or Chatroulette. My moves of choice are also those popularized by low-budget Chop Socky flicks and Street Fighter II.
But the most gangsta thing about this video is the circa 1993 Adidas shower slippers worn by Freddie. Check the 3:13 mark.
