A special package arrives for Butters from Japan. He opens the crate and it contains a robot named the A.W.E.S.O.M. – O 4000. AWESOM-O (whose voice sounds like Cartman) introduces himself and promises to be his new best friend. AWESOM-O wants to know Butters secrets and he is told about Butters' sphincter problem and other secrets, including the fact that he knows a secret about Eric Cartman, the kid who always picks on him. Butters has a videotape of Cartman dressed as Britney Spears dancing around a cardboard cutout of Justin Timberlake. AWESOM-O wants to know the location of the tape, so that he might make a backup and stuff. With Butters having this damaging videotape, Cartman commits himself to keeping up the AWESOM-O disguise until he can get his hands on the tape. Butters plays with his new "robot friend" in a musical montage and later that night, since he knows about the sphincter problem, Butters has AWESOM-O insert his medicinal suppository in his rectum. The next morning Butters wakes to find that AWESOM-O has trashed his room looking for the videotape. Butters spanks AWESOM-O for being a "bad robot." Stan, Kyle and Kenny stop by and Cartman tries to tell them that he has to pretend to be a robot for a little while longer. Kyle wants to know why. Since the boys are playing so well together, Linda Stotch asks Liane Cartman if her son can go with Butters to visit his Aunt Nellie in Los Angeles. Despite the fact that he has been grounded for trying to exterminate the Jews two weeks ago, she agrees to let him go. Butters' parents tell the news to the two boys, one of them is delighted, and the other thinks it "lame."
Butters and AWESOM-O arrive in Los Angeles and AWESOM-O barely gets some time alone in the bathroom, before he and Butters go sightseeing. At a movie studio Butters is showing off AWESOM-O to a crowd by letting them ask him questions. Some movie executives catch sight of this event and decide that AWESOM-O might be useful in helping them to come up with movie ideas. They bring Butters and his robot into their offices and they get AWESOM-O to come up with ideas. Most of AWESOM-O's movie ideas involve Adam Sandler. Butters takes the money they are making from pitching these ideas ($100 per) and sends it to needy kids. At the Pentagon they have found out about AWESOM-O and his abilities. They decide they want this robot for themselves and plan on turning it into a weapon. They also know that AWESOM-O has been developed by Japan; they are worried that the Japanese will turn it into a weapon before they do. Back at Catamount Studios AWESOM-O pitches another idea and then one of the executives clears the room. Alone with the robot, he asks AWESOM-O if he is "a pleasure model." AWESOM-O indicates he doesn't know what he means, and the executive proceeds to show him. AWESOM-O escapes the conference room only to be captured by the Army.
The Army is ready to see what makes AWESOM-O tick, when AWESOM-O comes back online. Cartman attempts to break his cover, but with his arms and legs strapped he can remove his head. The scientist thinks that AWESOM-O doesn't know he is a robot. They think that AWESOM-O thinks it human. The scientist is now against reprogramming the robot and turning it into a weapon. Meanwhile on the streets of LA Butters mourns the loss of his robot friend, when he sees the black van that captured AWESOM-O. The scientist decides to save the life of the AWESOM-O and the robot is about to reveal himself, when Butters arrives on the scene. Butters breaks down and tells the Army that they can't kill AWESOM-O as he is his best friend. The Army is about to relent their position and let AWESOM-O go when AWESOM-O does something uncharacteristic for a robot, he farts. Later, back home in South Park, to everyone's delight, but especially his own, Butters is showing his videotape of Cartman dressed as Britney Spears and dancing with the Justin Timberlake.
