"If Those Kids Could Read They'd Be Very Upset" is a popular meme originating from the animated sitcom King of the Hill. The specific scene is from Season 6, Episode 10, where Bobby Hill makes the titular remark as his father, Hank Hill, holds up a sign to a group of seemingly oblivious children. The meme's primary use is to humorously highlight a situation where a piece of information, a fact, or an opinion (represented by the blank sign) would be profoundly shocking, infuriating, or upsetting to a particular group of individuals, if only they were aware of or understood its implications. It's often used ironically to comment on ignorance, naivety, or a deliberate lack of understanding regarding a controversial or uncomfortable truth. The blank sign is typically filled with text or images to convey the upsetting content.
