Shuffling

How the hell do these ppl do the shuffle??! Shuffling looks so fucking hard..i can't imagine actually doing it...i think i'll look like a clown if i'm caught in the act of shuffling..n i also think my legs will get twisted together while doin the steps..hehehe...

Shuffling definitely looks cool n all..but its so complicated!! Geez..i need to master the art of shuffling!! anyone willing to share their expertise??
