The human microphone may be the best possible way to hear Zizek. The jokes, especially, are funnier when chanted by a crowd.
That said, he does give a concise account of the Occupy Wall Street protests:
"Beware not only of enemies, but also of false friends who pretend to support us, but are already working hard to dilute our protest. In the same way we get coffee without caffeine, beer without alcohol, ice-cream without fat, they will try to make us into a harmless moral protest. But the reason we are here is that we had enough of the world where to recycle your Coke cans, to give a couple of dollars for charity, or to buy Starbucks cappuccino where 1% goes for the Third World troubles is enough to make us feel good. After outsourcing work and torture, after the marriage agencies started to outsource even our dating, we see that for a long time we were allowing our political engagements also to be outsourced—we want them back."
Now if only Zizek could rally the Tea Partiers, maybe broker a joint protest.
