After 22 years, Jay Leno will step down from the Tonight Show next month. To mark the occasion, 60 minutes' Steve Kroft is filming a profile piece on Leno. According the Boston Herald's Inside Track, Leno paid a visit back to his first job in Andover, Mass this weekend. He worked at McDonald's there while he was a student at Andover High School...and customers were stunned to see him return to his old post at the drive thru.
