Y’know how titles of books are supposed to be italicized? (You do know that, right?) Well, this rule applies even when the title is mentioned in dialogue.
“It’s like Lord of the Flies out there.”
(If the title of a shorter work — short story, article in a periodical, non-epic poem, etc. — is mentioned in dialogue, write the title inside single quotation marks, since they’d be inside double quotation marks otherwise: “I’m sure my interpretation of ‘The Yellow Wallpaper’ was partly due to it reminding me of an illustration in a psychology textbook.” If you follow the UK English convention of writing dialogue inside single quotation marks, use double quotation marks for the title.)
