Examples: Itchy & Scratchy from The Simpsons, The Scary Door from Futurama, or The Grand Inquisitor from Dostoevsky.
If games count then all the radio stations in GTA
The lore books in The Elder Scrolls series, hands-down.
There is an entire universe of conflicting knowledge, personal bias, and unreliable narrators that leave Tamriel’s history feeling very real, and very open to interpretation. The fun of it is piecing together the truth somewhere in the middle. But I’ll die on the hill that the Arcturian Heresy is absolute horseshit written by a madman, and comparable to the scribbles of a paranoid schizophrenic on an anti-vax forum. Anyone who references that volume in regards to Tiber Septim and the forming of the empire is an impressionable dweeb.
McBain in The Simpsons is a classic.
This video stitches the movie together somewhat.
Springtime for Hitler, The Producers https://youtu.be/1zY1orxW8Aw

The Magicians by Lev Grossman
Fillory in the magicians trilogy by Lev Grossman is fantastic.
Surprised that no one has mentioned Vegemorphs from PBS’s Arthur yet.
Camp Pining Hearts from Steven Universe. Does Fiona and Cake from Adventure Time count?
As The Stomach Turns. It was a classic parody of soap operas on The Carol Burnett show, and as someone from that era i can vouch that it was a pretty spot on parody, at least from what i saw on tv when staying home sick from school.
Galaxy Quest the Show inside Galaxy Quest the Movie
Do the Justice Friends from Dexter’s Lab count?
