S4E14 Carl Wash

Two floating brains, both named Carl, enlist Meatwad to promote their rundown car wash. Unfortunately, he fails to draw in any customers. With Shake’s assistance, they convince one of the Carls to bring his vehicle in for a wash. However, the brains end up destroying his car, gassing him, and ultimately extracting his brain.
