"Five exclamation marks, the sure sign of an insane mind"
About this Quote
The line works because it’s a tiny, weaponized rule of taste masquerading as a diagnosis. Calling it “the sure sign of an insane mind” is knowingly outrageous, a satirical overreach that mirrors the very excess it condemns. Pratchett is policing the border between wit and noise, but he does it with a wink: the insult is so exaggerated that it becomes a parody of judgmental literary snobbery even as it indulges in it.
Context matters. Pratchett wrote in the shadow of British comic tradition and newsroom-style minimalism, where the exclamation mark is treated like hot sauce: potent, easy to overuse, embarrassing when sloshed everywhere. It’s also a pre-internet prophecy. Before caps lock and reaction GIFs, the exclamation mark was the mass-market tool for manufactured excitement, a hallmark of breathless advertising copy and melodramatic prose. Pratchett’s subtext: if your words can’t carry the emotion, no amount of typographical screaming will save them. The real sanity test isn’t punctuation; it’s restraint.
