No comment...okay okay maybe one comment... It's okay to admit that this video totally describes you. Weirdo. But if you don't wanna admit that, then you should at least check out the acapella group who did it, Penn Masala.
If you're brown and you've gone to college in the US, you've definitely heard of them. But just in case you can check them out at www.pennmasala.com where you can also download the song.
