This is pretty damn funny (but there's a barrage of bad language for the easily offended... FYI). Comedian Bill Burr is the third comedian to be booed endlessly by a crowd for no reason, before their act even starts while at a show in Philadelphia. Deciding he's going to do a different kind of "act" anyway, he hilariously tears the crowd a new one. I highly recommend checking out more of his stuff - Burr is a brilliant comedian and hosts a great (free podcast) The Monday Morning Podcast.
