Can a grouch find reason to enjoy the holiday season It's Christmas Eve on Sesame Street, and Oscar has just received a Ghost-o-Gram. He will be visited by three ghosts tonight: a famous British Grouch, a talking Christmas Tree, and a Robot. They will help Oscar examine Christmases past, resent, and future on Sesame Street. Will their adventures be enough to help Oscar put aside his grouchy says in favor of the holiday spirit?
