To help celebrate, Martha welcomed the hilarious late night host, Conan O’Brien. Conan joined Martha in the craft room to prepare the 272nd craft demonstrated on-set over the past three seasons, glittered eggs and a glittered ham! When commenting on the daytime time period that Martha’s show airs, Conan said: “This appearance today is a chance for my parents to see me on television, they watch Martha; they are not watching my show at 12:30 at night.”

Later in the episode Martha welcomed a very special surprise guest, President Bill Clinton. President Clinton helped in celebrating 500th episode by updating Martha and her viewers on the Clinton Global Initiaive and Mycommitment.org, a site that has garnered 90,000 visitors, including over 1000 commitments valued around $900,000 since Clinton’s last appearance on ‘The Martha Stewart Show’, back in September of last year.
