* "Series/{{Torchwood}}" has a particularly amusing example in the episode "Adam." Ianto keeps a diary, which is not surprising considering how precise and orderly he is.

* In the TraumaTeam game for the Wii, there's a Forensics chapter. The third case gets incredibly disturbing when the diary of [[spoiler:Alma]] is found, and it [[spoiler:depicts her descent into insanity, due to her prefrontal lobe tumor, from a loving mother and wife to a psychotic 'Beast of the Lord' who wants to kill her daughter and paraplegic husband in order to let them all go to Heaven together.]]

* In an issue of ''ComicBook/GenerationX'', the school is robbed, and Husk's diary is one of the items stolen. Since she often wrote about their adventures, everyone obviously treated this as a risk to the {{Masquerade}}. The thieves were eventually found and convinced to return the stolen items, and thankfully Husk's diary was written off as a bored schoolgirl's overactive imagination. The thieves ''did'' enjoy the PurpleProse dedicated to Chamber, however, and one proceeded to read it, embarrassing poor Paige as the Gen X kids died laughing (thankfully Chamber wasn't with them).
