In a take-off of Charles Dickens "The Christmas Carol," Mr. Spacely is being so greedy and selfish that he would even make Ebenezer Scrooge blush. On Christmas Eve, he's first haunted by his former (ghostly partner) Jacob Marsley (a blue humanoid alien who's now wrapped up in mummy bandages.) Jacob Marsley warns Mr. Spacely about the consequences of being greedy. Mr. Spacely is too full of himself to take Marsley seriously, so now he's going to be visited by (what a surprise, not!) three more spirits. First up is the Ghost of Christmas Past (A giant floating robotic head.) Second is the Ghost of Christmas Present, who literally looks like a Christmas present! Finally, the Ghost of Christmas Future (a tall, speechless mega-computer) appears and finally knocks some sense into Spacely. Spacely takes the true meaning of Christmas spirit to heart by showering gifts and presents on the Jetson's family, and everybody (predictably) lives happily ever after. (thetvdb.com)
