A Supposedly Fun Thing I'll Never Do Again: Essays and Arguments is a 1997 collection of nonfiction writing by David Foster Wallace.

He is uncomfortable with the professional hospitality industry and the "fun" he should be having, and explains how the indulgences of the cruise cause introspection, leading to overwhelming internal despair.

This collection also includes Wallace's influential essay "E Unibus Pluram" on television's impact on contemporary literature and the use of irony in American culture.

Tina Fey's 2011 memoir Bossypants includes a chapter on her own cruise experience, titled "My Honeymoon: Or, A Supposedly Fun Thing That I'll Never Do Again Either," in which she jokingly suggests that those who've heard of Wallace's book should consider themselves members of the "cultural elite."

In Charlie Kaufman's 2020 film I'm Thinking of Ending Things, the character Jake mentions the book, refers to "E Unibus Pluram," then recites a portion of the essay from the section "Image-Fiction" verbatim.
