When Shake plans to use his new exercise machine, Frylock notices that it is not assembled properly, and the instructions cannot be found. After searching for them online, he finds a message warning not to assemble the machine. Frylock calls the website's listed phone number, which is revealed to be that of Emory and Oglethorpe, the Plutonians. Before answering the phone, they discover the Cybernetic Ghost of Christmas Past from the Future on board with them. The Ghost explains to the two aliens that the machine, when assembled, will exercise a man into a super-being, who will attract all the women on Earth, leading to massive inbreeding and the eventual extinction of mankind. To prevent this, the Ghost travels to the past and steals a screw that holds the machine together. The Plutonians point out to him that the screw could easily be replaced.
