While I get the joke, as a technical writer, you might be surprised how often I've found myself as a defacto QA engineer:
Me: This is what you said it does, and this is what it actually seems to do. Which one is right?
Engineer: Shit.
Me: This is what you said it does, and this is what it actually seems to do. Which one is right?
Engineer: Shit.
Also helps if you fix the bug or change the behavior, the docs are still technically correct. I'm only partially kidding, I swear I've seen this a million times in documentation I read.
Sadly, monospaced fonts kill sarcasm.
