Carl is sleeping in his room when he is awakened by a robot that claims to be the Ghost of Christmas Past. He has come to show Carl what Christmas was like for Carl in 1968. A flashback narrated by the Ghost shows a young Carl opening his father's "present", which he hopes is a "new mommy", but instead is a piece of burba carpet, which his father says is also his dinner. Carl's father says that it's time to go to work and for Carl to put on his respirator. Carl begins crying as his father demands he dress for work, and suddenly an enormous robot foot stomps the room and lasers shoot everywhere. Carl acknowledges that he remembers eating carpet, but not the lasers and robots. The Ghost claims that the reason he doesn't remember "The War of Man Versus Machine," which raged through the early 1970s, was because at the time it was only a prophecy, but in the future, the past has occured. Carl reminds the Ghost that it's not Christmas at all, but in fact February. The Ghost leaves in a cloud of smoke, saying he'll be back.
Master Shake shows up to tell Carl that his pool is full of blood. Frylock determines it to be elfin blood. The ghost arrives and informs them all that he is responsible for the blood. Frylock asks him why, and he goes into a story explaining how thousands of years ago, an ape named "Sir Santa of Claus" that enslaved elves to make toys, then became lost and built his house in the exact spot where Carl's house currently sits. Meatwad is frightened that the whole story is true, but Frylock assures him that it's not true. The ghost changes his story, saying Santa is now a machine. Frylock reminds the ghost that he still hasn't explained the elf blood, and he says that it was due to the "great curcuiting". He then goes back into another story, and talks to the night, ending with an explanation of where babies come from—for machines. Everyone else has fallen asleep, but Meatwad is still engaged in conversation with him. When they awaken Frylock, they reveal that Carl's house was built on elf graves, and the ghost is haunting it because Carl desecrated the land. The only way to end it is for Carl to give himself sexually to the Great Red Ape
Carl would much rather move out though, so he packs his boxes. He gets ready to take a shower to get ready for some potential buyers for his house, but ends up covered in elfin blood. He ends up showing the house to Glenn Danzig. He explains the features of the house and the shrieking robot that comes with it, and shows him the pool, still filled with blood, which gets Danzig interested in buying the house. He asks for a price, and accepts Carl's offer of a million. He runs sprinklers which spray blood all over the front yard and house, and comes over to the Aqua Teens' house, looking for the robot. Shake says he hasn't seen him, but does show Danzig a haunted kitchen, which is Meatwad covered in a blanket with the lights flipping on and off, in an attempt to get Danzig to buy their house. Danzig gets angry and leaves. Meatwad tells the ghost to come out from the hallway. The ghost says that he is freaked out by Danzig, and Shake gets angry and orders him to make the house bleed.
- This is the first episode containing language censorship.
- Frylock tells Carl to go use his bathroom, but in previous and future episodes, it is revealed that the Aqua Teens didn't have a bathroom.
- In this episode, "Little Carl" asks his father if his present is a "new mommy," likely meaning that is mother is deceased. However, in The Clowning, he is seen giving a message to his mother. In Deleted Scenes (and the Deleted Movie), he is seen talking to his mother. He is also seen talking to his mother in Robots Everywhere meaning it is possible Carl's parents divorced
