Let's hope not. At least, if they do such an episode, it should be "why the nut cases were wrong", not the Mayans.
The current Mayan era of 5125 years ends in 2012, but their calendar didn't end then. The current era is one b'ak'tun, which falls within a piktun of 7885 years, which falls within a kalabtun of 157704 years, which falls within a k'inchiltun of 3154071 years. Saying the Mayan predicted the end of the world is like saying we predicted the end of the world because our 2012 calendar ends on 12/31/2012.
