This sign language interpreter has got some sweet moves.

This interpreter was signing the words to Swedish singer Magnus Carlsson's song "Möt mig i Gamla Stan" during the recent Eurovision contest. Only he wasn't just signing -- he was getting jiggy with it, totally getting into the tune and busting out some intense dance moves.

Why this guy is signing and not working as one of the back-up dancers remains a mystery to us because he brings a crazy energy all artists would love to have while performing.
