Carl Wash.Meatwad responds to an ad in the newspaper and gets a job at "Carl's Car Wash," standing out on the highway in front of it waving and dancing to attract business (but only gets cups full of coke thrown at him). The proprietors of the business, a large floating human-like brain named Carl and his son Carl Jr. (who talks in quick gibberish), feel their business is failing since Meatwad can only shape shift into a hot dog or an igloo. Meatwad gets some help from Frylock in trying some new shapes, but eventually gives up. He instead takes Master Shake's advice and tries unsuccessfully to antagonize their neighbor Carl into getting his car washed, by turning into a fist extending his middle finger then asking if he is a dumbass who's gonna get his ass whupped. Only when Shake completely covers Carl's car with dirt does he take it to the car wash. This a rare instance of Shake helping Meatwad without an ulterior motive or for personal gain (except perhaps the joy he gets from tormenting Carl). At the car wash, Meatwad has him lie down on a gurney with an oxygen mask as they both watch his car go through the wash: first getting the first half brushed, then covered in "dumpster juice" (which is a combination of rain water and garbage, and is very acidic, and very harsh on the paint job), then cat urine, then getting smashed with hammers, then being repainted in a 'color of their choosing'. When Carl protests, gas pumps into the room, and Carl and Carl Jr. arrive and, after pointing out that he, his son, and Carl have the exact same name, demand his brain be removed (a demand which shocks Meatwad).
