Lots of people crying that their mascot, Beck, was shown to be hypocritical.
The punchline of the video is that he is clearly amazed that the Arizona immigration law is being compared to Nazi Germany, yet Lewis Black shows several videos within the past 2 years where Beck compares everything to Nazi Germany and references Hitler in most of them. If you can't find that funny, then you're probably a hack.
Also, make sure you get your shots of Olbermann in there, we wouldn't want to upset the delicate balance of talking heads now would we? It reminds me of my grade school days where the best comeback was "No, YOU are!" *oooooo*
