Bobcat Goldthwait's 2009 commencement address for Hampshire College is off-beat and definitely worth the listen. Be patient – the last five minutes are worth it.
Every decade or so – maybe more often, but I'm too tired to research it – a movie comes out that seems to capture the zeitgeist in America. Good examples would be 1987's Wall Street or 1993's Falling Down and after seeing the trailer for Bobcat Goldthwait's God Bless America (definitely NSFW with a few f-bombs and mega violence) I'd say it captures our current reality-tv-fueled society quite well.
Come to think of it MIchael Douglas seems to be in a lot of zeitgeisty movies.
