This is what happens when a character tricks another character by writing a letter and signing it under a different name. Sometimes, the real writer's own handwriting was recognized, making the letter a big lie to the reader.
Anime And Manga
- In El Hazard's first episode, Makoto walks blindly into a trap, after receiving a love letter from his childhood crush, Nanami, asking him to meet her alone, after school. In truth, the letter was from her brother, Jinnai, who reveals it was one of several, from her ample collection of 'practice notes'. At which point, Makoto correctly guesses she had written them as part of a 'creative writting' assignment.
- In Sunset Boulevard, the fan letters that Norma had been getting over the years were actually written by her butler Max to spare her from the fact that the public had forgotten her.
- In Red Riding Hood, Valerie's sister is tricked outside at night by the wolf when he forges a letter from the boy she's in love with.
Live Action TV
- In the book of Ella Enchanted, Ella realises that if she were to marry Char, her curse would make his life difficult and even dangerous. So she writes a letter in her own handwriting, claiming she's run away with a rich lord, then writes an accompanying letter in her stepsister's handwriting, terrible spelling and all, to back it up. It doesn't work. He just thinks the letter from her is fake, instead.
- On Dont Trust The B In Apartment 23, James gets a letter each year from his Dawsons Creek castmates inviting him for a reunion show, which he always rejects. Turns out the letters were actually from Chloe, which she uses as an excuse to get James to do whatever she wanted to cheer him up.
- In the Professor Layton game Professor Layton and the Lost Future (or Unwound Future), Clive pretends to be Luke from 10 years into the future, he writes a letter dated ten years into the future requesting the esteemed Professor's help and signing it as his apprentice, including an address which contains a lift to below the tube, where the 'future' has been built and Clive attempts to get revenge on Professor Layton by pretending to be the boy closest to him. There is an actual time machine though.
- In Team Fortress 2, sending a "tear stained letter" each to both his brothers is how Grey Mann convinced his two brothers to meet and reconcile so he could kill them both.
- In the Anaksha Mini-Adventure "Quick Stop," Anaksha does this to save the job of a convenience store clerk who did her a good turn by allowing her to use the store's restroom, which is normally reserved for employees only, but was ratted out by her rather crankish co-worker. The document in question is a letter of apology, which some unscrupulous employers use as a trick to get a signed confession out of someone so they can have a legal excuse to fire the person anyway, denying them any grounds for a lawsuit. Anaksha does this to allow the clerk an "out" in this should they indeed decide to fire her, and offers her a job at the Zaranna Corporation in case all else fails.
- In one of the Three Little Pigs shorts, the Wolf captures two of the pigs and writes a letter to Practical Pig pretending to be from his brothers in an attempt to lure him out. Practical doesn't fall for it: along with the bad penmanship, he recognizes the Wolf's breath when he blows it under the door.
- Avatar The Last Airbender: Sokka attempts to pull this in "The Runaway" episode, in order to patch things up between his sister Katara, and their friend, Toph. So he writes a fake apology letter and sends it to Katara, via messenger hawk. It fails hilariously, after she reads it and points out a rather obvious oversight in her brother's plan:
Katara: (shouts, while pointing at fake apology letter)
"I know this is from YOU, Sokka! TOPH CAN'T WRITE!!
