Ahead of their impending comeback tonight on M! Countdown, the Wonder Girls have released a dance tutorial for their newest single, 2 Different Tears through their Daum fancafe recently. It's been a while since we were infected by the easy-to-follow dance moves of Tell Me, So Hot and Nobody from 2007 - 2008. Can the girls create another dance phenomenon with 2 Different Tears in 2010? http://www.youtube.com/watch?v=Qt1eNhVNkBI
