Unfortunately, you're right about as much as the original meme is. At my current gig, I've worked with half a dozen PMs, and while the majority of them were (seemingly) sweet and nice people, at least half of them would struggle to pour piss out of a boot if you wrote instructions on the heel. Even with project templates and runbooks, we still regularly had to clean up after them because they didn't do part of the project or expected us to work on stuff that wasn't marked as being live yet.
