Vincent Pastore bailed on Dancing With the Stars after he realized that it would require physical activity. Luckily, Dancing was able to fill the void left by Pastore by recruiting John Ratzenberger, famous for his role of Cliff Claven on Cheers, as well as a multitude of Pixar film voice work. Pastore left after just one week of rehearsals when he discovered that it was a bit more than what he signed on for. Ratzenberger, 59, was asked to appear on the dance competition before, but had to turn it down due to a scheduling conflict. It’s good that he was free this go-around, and able to slip in quickly at the last minute. Tune in on March 19 to see how Ratzenberger and fellow Dancing contestants Joey Fatone, Billy Ray Cyrus, Heather Mills, and others make out in the big dance-off.
