Good-Bye, Diarrhea is the fourth "episode" of C.E. Forman's Lost Season One (of The Lost Seasons series), written in fall of 1998. Like all of Forman's Lost Season episodes, it is written in quasi-script form with three Acts and commercials.
In a departure from the television series, this story is set in Highland and recalls Daria's last days before moving to Lawndale. Included are prominent characters on Beavis and Butt-head, such as Beavis and Butt-head themselves and Mr. Van Driessen. The story is told in the style of a "Beavis and Butt-head" episode, with pauses for music video commentary (not included in the fanfic). Helen, Jake, and Quinn interact with Beavis and Butt-head, whereas they never did in either Beavis and Butt-head or Daria.
