If you rotate the figure 6 so it is upside down, you get a 9, and vice versa.
This trope is about those cases where confusion between these two numbers becomes a plot point. The most common (but not the only) scenarios:
- Causes some sort of confusion in the plot, that doesn't allow it to advance (like the example below).
- It's used for The Reveal or a Plot Twist. Often, but not necessarily, is the Number of the Beast.
For example: Alice is a detective and has learned from a phone call that weird things are happening in Apartment 6. She goes over there and investigates, but finds nothing. But the phone calls continue, so Alice goes again to Apartment 6, but finds out that the apartment where she was investigating was number 9, but the "9" somehow was unscrewed before and looked like a 6.
This trope also covers any other symbol (or collection thereof) that could be misinterpreted if read at the wrong angle, such as M and W.
Not to be confused with LOL, 69 (especially since that number is immune to this trope).

As Yuuma takes the stage, we see Minato crumble into dust.
- In Kinnikuman, Buffaloman uses this to hint at how he's going to defeat the Kinniku Buster, Kin's iconic move; Just as you turn a six into a nine by flipping the number upside down, so can the intended victim of the move reverse it on the one performing it!

- In an episode of Brave Police J-Decker, Yuuta suspects artist Ninomiya Mutsuky as being behind a string of art thefts, as his art was exhibited at all the museums that were hit, and an sculptor's knife was found at one of the crime scenes with the initials N.M.

Priest: Life's like that sometimes — one bad joke.

- In Fahrenheit (aka Indigo Prophecy), a Timed Mission puts police detectives Carla and Tyler in a hotel attempting to find the protagonist, Lucas, who is hiding in room 369. The player controls Carla/Tyler, but the first "room 369" you enter has someone else inside; the lettering on the door un-sticks and swivels to reveal that they're actually at room 366.

- Pops up every so often in the Professor Layton games. If a puzzle requires you to manipulate a set of numbered tokens which can be freely rotated, it's probably a good idea to assume this trope is in play.

And sure enough, customers start flooding through the door at 9.
- Nine Hours, Nine Persons, Nine Doors revolves around a set of bracelets numbered from 1-9, but not everything is as it seems:
- Late in the game, a #0 bracelet is introduced, but it acts as if it were #6. It's actually the letter O.
- Immediately following this, one character theorizes that June's #6 bracelet is actually a 9, which allows her to open any of the doors in the game, which in context implies that Santa's #3 bracelet marks him as Zero. This theory is mostly correct, but it's the other way around. Santa is the real #9, and June from nine years ago is the real Zero.
- This comes to a head when the final door with an apparent "9" on it turns out to be a "q". In Japanese, the number 9 can be pronounced as kyuu, while in English it's easy to mistake the two.

- The 'W' and 'M' were allegedly mixed up in "Mermaid Man and Barnacle Boy IV" as well; when SpongeBob shrinks people and things with Mermaid Man's belt, Patrick tells him he has it set to M for "mini" instead of W for "wumbo." This doesn't seem to do anything, but Mermaid Man's later comment indicates there really is a "wumbo" setting.

- In "Moving Bubble Bass", Bubble Bass Tricks SpongeBob and Patrick into heping him move his belongings from his mother's basement to his grandmother's basement. The address Bubble Bass gave them was house #166, but because SpongeBob and Patrick were holding the paper upside down, they mistake house #991 for the proper address, much to the chagrin of the house's owner.
- There is also another example of 'W' is 'M' in The New Scooby-Doo Mysteries episode "A Nutcracker Scoob". Daphne finds a lapel pin on the floor with the initials W.N. on it, which everyone believes stands for Winslow Nickelby. In the end, it turns out that they were holding the lapel pin upside-down so the correct initials were N.M. for Nanette Musette.

- In the Futurama episode "A Big Piece Of Garbage", the crew are sent to blow up the titular ball of garbage set to collide with the Earth. Unfortunately, they end up nearly getting killed due to Professor Farnsworth having set the timer while the screen was upside down.

- The Simpsons:
- The official answer to "Who Shot Mr. Burns?" involves a clue where Burns left when he fell on the town sundial, pointing to W and S which implicates Waylon Smithers - except from his angle, he was pointing to M and S for Maggie Simpson, the true culprit. Notably, they actually did consider this before, since it could still have implicated Moe Szyslak, Sideshow Mel, or even Santa's Little Helper (referred to by Mr. Burns as "that Simpson mutt") as a Red Herring.
- Exaggerated in "Mother Simpson", where Chief Wiggum reads Homer's entire name upside down.

- In "Bart the Genius", after Bart gets a high score in an IQ test (by switching his answer sheet with Martin's), the school counselor shows homer the results.
