The insightful part is this:
"What’s a joker? A joker is someone who says they’re going to do something, and then doesn’t. A joker always has excuses. “Oh well, I tried…” -> No, I don’t give a fuck that you tried. Did you do it or not?
DID YOU DO WHAT YOU SAID YOU’D DO OR NOT?
If not, you’re a fucking joker and we’ve got problems."
True, though I'm not sure that's the generally accepted definition of "joker." I think this screed could be better summarized by the catchphrase "Git 'r done!"
Ironically, said catchphrase was created by one Larry the Cable Guy — a noted comedian, or professional "joker."
A problem might be that "it" in the mind of the manager is a clear cut, black and white thing, whereas in reality it might turn out to have more facettes and nuances. With a bulldozer manager (get it done or get out) it might be difficult to adapt to reality.
I also dislike that kind of speeches because it sets up a power hierarchy from the start. Not a good basis for cooperation.
DID YOU DO WHAT YOU SAID YOU’D DO OR NOT?
If not, you’re a fucking joker and we’ve got problems."
To summarize: don't talk about it, be about it.
