Basically this episode is about how Americans LOVE celebrites. Black celebrities in particular (OJ Simpson) often invoke racism and claim they were framed. Strangely, this defense only works for performers, not for activists. In this episode, it's about the trial of R Kelly. For those who haven't seen the news, R Kelly was charged with several accounts related to a "golden shower" incident with a minor. He even filmed it.
The jokes were funny on a number of levels, from the lawyer talking about the prosecutor's white wife (since it obviously makes everything okay that R Kelly was molesting a black girl) to the news giving a URL where you can find the video (which happens to be just how seedy 24-hour networks are).
