This is one of the few songs I like better done by the cast of "Glee" than by the original artists. It's such a cool song. Whomever wrote this, they certainly opened up the eyes of young men everywhere to the things women fight about with one another. I have a freakin' Ph.D. in Applied Human Behavior and still pretty much have to say there's only one thing I know for certain when it comes to women and romance, and that is that I know absolutely NOTHING for certain about women when it comes to romance, but this song is a bit of a keyhole into that behavior. From the popularity of the tune, I can only guess there's a great degree about it which is accurate re: women and romantic behavior. Any females want to speak up on that topic? :)
Santana is amazing in this song. But what did not make sense about the performance of this song is if her and Mercedes were fighting over Puck in this episode, how did they ever get together to perfectly choreograph a song for Glee Club? I mean really, Ryan Murphy? Your better than that.
