I don't know if this was mentioned in the thread that started this one, but another phrase used to control was, "yes, thats good, but is it best?"
Geez, how I hated that. It always meant that what you wanted to do was wrong and what they wanted you to do was "best." Cause the devil doesn't make you choose between good and evil, but between good and best.
My skin is crawling right now, just thinking about it.
