Don't make me tap the sign

This meme features a character (often a bus driver from "The Simpsons") tapping a sign with a repeatedly stated rule or obvious truth. It's used to express exasperation when a basic, well-known fact or rule needs to be reiterated. The meme conveys a sense of "I shouldn't have to say this again." Its humor comes from the relatable frustration of dealing with ignorance or intentional disregard. Creators often compare it with Woman Yelling at Cat for exasperated explanations, or with Change My Mind when a fundamental truth is being challenged. The format's strength lies in how it adapts to different scenarios, much like how This Is Fine has evolved to meet modern content creation needs.
