(The complete plot for this South Park Episode)
The episode starts with Cartman playing a prank on Butters by disguising himself as a robot named "The A.W.E.S.O.M.-O 4000" and by putting himself in a crate on Butters's doorstep "from Japan". Cartman is planning to befriend the gullible Butters and discover his embarrassing secrets, so he can blackmail him and/or embarrass him in school. Though Butters acknowledges that his birthday is "not until September 11", he enthusiastically accepts this deception and reveals several personal secrets. However, Cartman's prank backfires when Butters reveals that he knows one of Cartman's secrets - he has a videotape of Cartman doing a Britney Spears dance routine to a life-sized cutout of Justin Timberlake while dressed as her, which he plans to show to his classmates the next time Cartman plays a prank on him, which Cartman is already doing.Cartman, terrified about Butters' plan of revenge searches desperately for the tape but to no avail. Cartman soon is starving because Butters believes that, since he is a robot, he does not need to eat. Butters also forces the robot to do all his chores for him, including some of the more unpleasant tasks. With the agreement of Cartman's mom, Butters' parents (knowing who AWESOM-O really is, but thinking it an elaborate game that Butters is in on) decide to let AWESOM-O come along with Butters on a trip to Los Angeles to see his aunt. Cartman realizes that he will have to accompany Butters on the trip, in order to keep up his disguise. Upon arriving, he is so hungry and worn out after wearing the suit for a whole airplane ride 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.
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 fa99ot!" to a humiliated Cartman. Cartman responds by saying "Lame!"
