In the novel "Catch-22" by Joseph Heller, Major Sanderson converses about fish in a rather disheartening manner. When asked what a particular fish reminds him of, he can only think of other fish, leading to a cycle of thought that becomes increasingly unfulfilling. This circular logic highlights the absurdity that pervades his experiences, showcasing how repetitive and mundane his interactions have become.

Sanderson’s indifference to fish reflects a deeper dissatisfaction with life. His admission of not particularly liking fish underscores the theme of disconnection and the search for meaning in an absurd world. The conversation serves as a metaphor for his entrapment in bureaucratic and repetitive systems, mirroring the broader struggles faced by the characters in "Catch-22."
