A few years ago, I took my niece to see Frozen. I loved the movie. Mostly because it was cool moment I had with the women in our family and my niece who was battling cancer at the time.

I was one of the few men in the audience. Later, I watched on the internets as many men were forced to watch with their daughters and began to sing some of the songs. The songs easily get stuck in your head.

One of them, "So, You Want to Be a Snowman" got the mashup treatment the other night. Dave Grohl was guest hosting as David Letterman and was interviewing Kristen Bell, star of Frozen, when they decided to ROCK OUT!

Damn. Dave Grohl looked JUST LIKE David Letterman.
