Since its debut in 1969, celebrities have been an integral part of Sesame Street. Famous faces often drop by Sesame Street to help entertain, educate and engage audiences of all ages. The show is now entering its 40th season, set to debut on PBS in November 2009, and the list of stars planning to stop by the street just continues to grow. The upcoming season will feature appearances by Adam Sandler ("Bedtime Stories"), Jimmy Fallon ("Late Night with Jimmy Fallon"), Ricky Gervais ("Extra"), Jason Mraz (musician), Judah Friedlander ("30 Rock"), and many others. I will be sure to keep you updated with details on this exciting landmark season as more information become available.
