"Crossed eyes, protruding tongue, Napoleon hat?"
This is how neurotypical people actually perceive mentally ill people. Mentally ill people would be surprised to find out this is true but it is. This isn't a cop being a totally ableist prick in 1887! It's just a cop describing how a mentally ill person would look to somebody who wasn't mentally ill. It's just facts, ma'am.
"Napoleon hat"
What was the last generation who understood the shorthand of somebody thinking they're Napoleon meaning they were crazy? Most Gen-Xers probably learned this (like they learned 80% of everything) from Looney Tunes. Was there a cartoon that kept this trope going for Millennials? Did Sponge Bob ever see Squidward with a Napoleon hat? What about the Rugrats? Doug? Rocko? Pete and/or Pete? Being that it's a mental illness called Grandiose Delusion, people today would not think they're Napoleon. They'd be Taylor Swift or Kanye West or Harry Potter. But back in the 1800s, Napoleon was one of the major go-to figures to think you were, if you thought you were historically important.
