CBS is already thinking about the fall 2006 TV season and has made a 13-episode commitment to a sitcom from the creators of Friends (David Crane) and Half & Half (Jeffrey Klarik). The Class will follow a group of twentysomethings who, having first become friends in the third grade, are reunited after losing touch with one another over the years. Throw in a murder mystery and a unique narrative twist and you've got Fox's Reunion.
