Ricky Martin Covers LMFAO on 'Glee'

As you're surely heard about a million times, Ricky Martin will appear on this coming week's episode of Glee, playing a Spanish teacher who helps the kids perfect their tongues for a song. And he himself can't help but sing along. No offense to Senora Helms, but if Spanish teachers looked like Ricky Martin when we were in high school, we would have studied a lot harder.
