Music never looked so good.

A big part of sign language is conveying emotion via facial expression. So it makes sense that signing a song requires even more physical communication to portray the feeling, beat and overall spirit of a piece of music. And there's no song that's more catchy and fun than a Eurovision Song Contest song.

All of which resulted in the most thrilling performance ever by Tommy Krångh, a sign language interpreter for the final round of the Swedish Eurovision competition, on Saturday night.

Something about Krångh's commitment to his job, combined with his refined glasses-and-bowtie combo, is more fun to watch than any Eurovision song ever was, and the video quickly went viral. Can a signed song get stuck in your head?
