Alice writes Bob an unsigned note, typically a secret admirer type message. Carol finds the note, misinterprets it and believes it was written by David. The note continues to be passed around until all characters have misconceptions about one another.
- A variation is played on Haruhi Suzumiya, when the class representative Ryoko Asakura leaves Kyon an anonymous note in his Inside Shoes locker. Kyon first thinks the note was written by Mikuru, but then he corrects himself: the note was a simple sheet of paper torn from a notepad, and it would be Mikuru only if the note was written in scented decorated paper sprinkled with glitter. Massive mayhem ensues. Decidedly not of the romantic variety.
- Some of the mayhem is of the romantic variety, or at least looks a lot like it.
- He later finds a letter actually written in decorated paper by Mikuru... only problem is, he's only partially right...
- Another variation occurs in Love at First Sight, where a lovestruck man dictates a love letter to Yuki to Kyon. Naturally, this means Kyon writes the letter in his own handwriting. It led to some awkwardness when explaining the situation to Yuki, but it got worse when he threw it out and Haruhi saw it.
- Happened in P. G. Wodehouse quite frequently.
- Our Miss Brooks: The plot of "Bones, Son of Cyrano".

- The Comic Strip Presents film Mr Jolly Lives Next Door features an escort agency accidentally receiving a letter meant for a hitman. The message? "Take out Nicholas Parsons".
- In Full House, a prank love letter was left to one of the girls. It then gets delivered to the wrong girl, who distresses over it and misplaces it. Repeat for every other character on the show, except the intended recipient.
- In an episode of My Name Is Earl, Earl helps a man who'd written a love letter Earl had prevented from being delivered by spending time with the intended recipient so she won't get involved with anyone else before the sender can get back into shape again. When she finds the letter, she thinks it's from Earl. Unfortunately, Earl's interested in her, too — she can spit and she likes Lynyrd Skynyrd! — so he lets her go on thinking he'd written it.
- Final Fantasy IX, in which Eiko leaves a note for Zidane. It never reaches him, and is eventually intercepted by both Steiner and Beatrix, who each think it's from the other.
- Incidentally, the game was greatly inspired by Shakespeare, who absolutely loved this kind of plots.
- In one episode of The Simpsons Lisa develops a crush on school bully Nelson. She is too scared to approach him and so writes a "Guess who likes you" note and asks Milhouse to pass it to him. Nelson does not realize that Milhouse is acting as an intermediary and so the resident Butt-Monkey ends up in the hospital.
- In an episode of Total Drama, Bridgette and Gwen find a love poem, and each believe it's from their respective love interest. Hilarity Ensues as they try to prompt Geoff and Trent into admitting it. Turns out it was from Harold to LeShawna
