Cartman dresses up like a robot named AWESOM-O and moves in with Butters. His plan is to learn all of Butters' innermost secrets and then use them against him. While Butters is thrilled to have found a new best friend, the U.S. Army believes AWESOM-O is a new secret weapon and Hollywood is after the phony robot to develop their next big blockbuster.
Template:Spoiler Cartman disguises himself as a robot named "The A.W.E.S.O.M.-O 4000" and puts himself in a crate on Butters's doorstep with a Japanese address, planning to befriend a gullible Butters and thereby discover Butters's embarrassing secrets (presumably so he can blab them to everybody at school). However, Butters also tells "AWESOM-O" that he knows one of Cartman's secrets—he has a videotape of Cartman dressed up like Britney Spears, making out with a cardboard cut-out of Justin Timberlake. Butters reveals that he plans to show the tape to the town next time Cartman plays a prank on him.
Cartman, terrified about Butters's plan, searches Butters's room furiously for the tape (while having the robot suit on, or Butters will know "AWESOM-O" was another prank) but fails. Meanwhile, he starves because Butters believes that he is a robot and doesn't need to eat. With agreement from Cartman's mom, Butters's parents (knowing who "AWESOM-O" really is but thinking it's an elaborate game that Butters is in on) decide to let "AWESOM-O" come with Butters on a trip to Los Angeles to visit his aunt. Left with no alternative, Cartman is forced to go, or else reveal his disguise. Upon arriving, Cartman is so hungry and is feeling terrible (as traveling on a flight in a robot costume is obviously not pleasant) that he makes up an excuse to use the bathroom and proceeds to eat toothpaste.
In Hollywood, movie producers hear about the "robot" and decide to hire him from Butters to create movie ideas; Cartman, as the robot, pitches over one thousand nonsensical ideas (800 of which star Adam Sandler), while the movie producers are gullible enough to buy them. Meanwhile, the United States military hears about "AWESOM-O", and decides to capture him to make him into a weapon. "AWESOM-O" flees the movie studio in panic after a film producer tries to sodomize him, thinking that he is a "pleasure model". The military captures "AWESOM-O" by shocking him, and abduct him into a secret base.
Cartman tries to explain that he's really a kid, but the military believes that Cartman is a robot with A.I. that made them think he was human. A scientist attempts to save Cartman. Cartman is about to reveal that he is a human when Butters shows up to rescue him. Cartman has to keep his disguise, allowing the military to kill the scientist (because he tried to stop the military from converting "AWESOM-O" into a weapon).
Butters pleads with the military to spare "AWESOM-O" and the general is touched. At this point, Cartman farts, causing Butters to suspect and finally reveal his true identity. Cartman tries to cover it up, but fails. Butters carries out his promise and shows the video of Cartman dressed as Britney Spears to the whole town, as well as to the movie producers and the military (because they met "AWESOM-O" too). Butters celebrates his victorious revenge on Cartman, who is laughed at by everyone. The general, who had come to South Park to see the tape, says, "Wow, kid. You're a little faggot!" to a humiliated Cartman. Cartman responds by saying "Lame!"
