Is Oreo Whisper Fight the Funniest Super Bowl 2013 Commercial?

Oreo's Super Bowl 2013 commercial features a "whisper fight" in a library that breaks out over whether the cream or the cookie is the best part of the glorious whole that is the Oreo. It's nice to see that even having such strong feelings on the issue, every single person involved is mindful of keeping it down in the library.

So which is it? Cookie or cream? You can pick your side on Instagram.
