If you have not seen the show, any of their videos on youtube, or heard their songs on the radio you are missing out and you need to watch this video. If you have seen or heard them then you will watch this video because you know it is freakin' hilarious. (Yes it is that funny). Actually I think I shall put two videos up. These are my favorite. Just as a warning the humor is dry.
