"Never ask a good question, unless you're ready for a stupid awnser."
Reasoning: Chances are it's probably been asked twenty million times before giving a stupid awnser more than enough time to formulate.
This realisation came from sort of trial by fire experience. I guess that may be the wrong way to put it. It was more a lesson derived from repetitive concussions experienced from beating my head against management walls.
After asking the same question myself and getting shot down by the powers that be, I got asked the very same question from someone working with me.
My response was "Good question. Don't ask it." Hence the axiom "Never ask a good question."
