Michael Richards of Seinfeld fame appeared via satellite on the David Letterman show when Jerry Sienfeld was a guest.  Richards offers an apology regarding his racially charged outburst directed at hecklers during a routine at a comedy club.  The incident received widespread coverage in the news and Richards' reputation took a serious hit.  In this rather awkward appearance (some of the audience is chuckling thinking something funny will happen), we ran the Believability Meter to see how sorry he really was.
