I would like to reference something a character said in a famous childhood story, e.g. The Boy Who Cried Wolf, or, Goldilocks and the Three Bears etc. amidst normal writing.
For instance, I'll use "proverbial" below, but I'm neither sure it makes sense, nor positive it's grammatically correct. I'm also unsure a drop-in replacement exists, but I'm hopeful.
Ex.1. Don't keep crying for the proverbial wolf, Dave, or us villagers on the marketing team might just stop paying attention.
Ex.2. Looks like that part of our software isn't tuned correctly. The proverbial porridge might be just a little too hot. I'll get it just right by next Friday.
