How low can you go?
Is there anyone older and wiser and still on the microphone with as much vengeance as pop cultural icon Joan Rivers? There is not! Her comedy career dates back to the freaking Ed Sullivan Show. While her touring and television appearances have not slowed, the world is divided on the Rivers camp. Some can't get enough of the irreverent 80-year-old and others cringe at the thought of having to stare at her face in person for an hour.
One thing is for sure, throwing Rivers into the Kravis Center was a major shift in the dynamic. Her audience was densely populated with the exact people that she targets: her peers. That's right, Joan might be the oldest in the game but that doesn't stop her from hating old people. In fact, she hates a lot of groups. We all do, but at least she has the cajones to say it.
