- In Good Omens, the local newspaper serving Tadfield has a surprisingly specific horoscope for Libra, on the day the apocalypse begins.

- In The Light Fantastic, the University's astrologer reads Rincewind's horoscope in hope of tracking down his location. It rambles a bit, but warns those born under the Small Boring Group of Faint Stars not to annoy any druids twice, which is very good advice for someone in Rincewind's circumstances that day.
- Black Hole High. Lucas shoved off a school assignment and submitted silly horoscope predictions to the school paper instead of a serious article and made them obviously about his friends. Because the school sits on a do-anything-black hole they came true. And he made a typo saying one of them would die rather than diet.
- In the first episode of the Dirk Gently TV show, one of the cases involves a man whose horoscopes are always coming true. Gently tries to convince him that it's a Self-Fulfilling Prophecy - he had an affair because the horoscope said he would, not because he wanted one.
- One episode of Psych has Shawn going semi-undercover at the local paper as a horoscope writer. When Gus criticizes his horoscopes for being too specific, Shawn replies that he wrote them with specific people in mind.
- A skit on the 80s UK sketch show Little and Large had Eddie Large impersonating 80s UK fortune-teller Russell Grant, with increasingly specific and bizarre horoscopes, including "And tomorrow, you will die".

- Episode six of Welcome to Night Vale features a horoscopes section where each of the zodiac signs are given increasingly odd/hilarious horoscopes. Among other things, Cecil warns Capricorns that "those were not contact lenses you put in this morning", announces that its Taurus's "annual crime day" where they're exempt from all laws, and simply curses Scorpios and their families and calls them "vile" for no understandable reason.
- The Onion loves this one. Every issue has an insane horoscope.
