How many engineers does it take to fix a bug?
Hardware Engineers: "None. We'll fix it in firmware."
Firmware Engineers: "None. We'll fix it in software."
Software Engineers: "None. We'll document it in the manual."
Technical Writers: "None. The user can figure it out." etc.
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.
