The drug addiction of
Towelie, a living and talking towel, is growing so overwhelming that the South Park boys make attempts to help him. Towelie's history is shown, using head interviews and on-screen captions (in a parody of Intervention), starting with years of drug addiction to
crack. He previously had a girlfriend named Rebecca and conceived a child with her (a
washcloth), but he was kicked out of their home due to his persistently getting
high. Having run out of money for
hard drugs, Towelie starts getting high off of cans of
computer duster. His life continued in a downward spiral, leaving him in heavy debt and offering
oral sex to strangers for money in the alleys. The boys help him get a job at Lake Tardicaca, a
summer camp for kids with
mental disabilities, as a towel to dry off the campers. However, Towelie persists in drug use and fellating strangers in the supply closet, and is fired by the camp. The boys confront Towelie and make emotional speeches to him as a plea to help him from killing himself (except for
Cartman, who uses this opportunity to read what appears to be several tens of thousands of pages of anti-Semitic remarks on television, which the psychiatrist allows to continue in respect of the "no interruptions" rule). Towelie refuses their pleas until
Butters reveals he has brought Towelie's child, "Washcloth", which finally prompts him to accept the offer to go to a rehabilitation clinic in Southern California. Later, Towelie reveals he has completed rehab and is now living with his girlfriend and son.
Meanwhile, at the summer camp, young bully Nathan and his lackey Mimsy plot to destroy
Jimmy during the athletic competitions so Nathan can be declared the camp's champion. This sub-plot is also narrated in the same style as Intervention. Nathan uses Mimsy as a minion to carry out his plans to harm Jimmy, but is repeatedly foiled by Mimsy, who either misinterprets his instructions or takes them too literally and causes his plans to backfire. Nathan tries to plant a black mamba in Jimmy's canoe during a race, but Mimsy instead leaves it in Nathan's canoe (when told to put it "in the canoe"). Subsequently, Nathan tries to lead Jimmy's team into dangerous Indian territory during a scavenger hunt, but instead Mimsy switches the maps and switches them again (Nathan demanded him to "Switch the maps! Switch the maps!"), and leads Nathan's team there. When Nathan tries to use a whistle with a shark
mating call against Jimmy, Mimsy, who was supposed to blow the whistle underwater, instead swims in the water briefly then blows the whistle on land and a shark jumps out of the water and
rapes Nathan with its nine-inch long penis, according to the Colorado National Wildlife Association. During the talent show, Nathan rigs Jimmy's
C-4, hoping it will explode during a solo, but when Jimmy cannot perform the solo correctly, Mimsy starts to show Jimmy the correct notes. Nathan interrupts and confronts Mimsy about his failure to follow orders. With a lapse of judgment, Nathan plays the correct notes and causes the ukulele to explode, knocking him away before being further injured by his past plans attacking him again. The ukulele solo is spoofing the Looney Tunes repeated use of the Xylophone gag, where the last note of
Believe Me If All Those Endearing Young Charms, is booby trapped, but the protagonist always somehow manages to play it wrong. Nathan is subsequently escorted to an
ambulance, but is given the champion's crown by Jimmy. Nathan tells Jimmy he hates him anyway before he is sent away to the hospital.
