It was a lot of fun once they started playing. Having to sit through being in a Jimmy Kimmel was lame but worth it. If you notice when they swing over to the band from Jimmy, there's a red roped off area keeping people away from the stage, that was knocked over about 10 seconds in and everyone was going nuts singing along. The security guards looked helpless and tried to get everyone back behind the rope but were not successful. Before they played Problems, they had to put the rope back up and asked everyone to stay away from the stage so they can get better shots. They closed with Pints... and everyone went nuts and knocked over the rope again, at that point the security figured there was nothing they could do and let everyone have fun.
