Joe Marley delivers three "Ghost-o-Grams" to Oscar the Grouch to teach him how to appreciate the joys of Christmas. The first ghost to visit Oscar is Rhubarb, the ghost of Christmas Past. Rhubarb plays old Christmas clips that show Oscar how to give from the heart. Next, the Ghost of Christmas Present, Christmas Carole, visits Oscar. She shows clips representing the importance of family, friends, and different holiday traditions. The final ghost is Sam the Robot, the ghost of Christmas Future. He plays an animated bit about what Christmas will be like in the future. Oscar finds that he does enjoy Christmas Day after all! Specifically, sticky balls of used wrapping paper and mushy snow. In the holiday spirit, Oscar gives Joey Dickens a smelly shoe and wishes him a Grouchy Christmas!
