I concur. And I'll pass. "Acting with integrity" as compared to "don't be a grin fucker" hasn't exactly lost it's ring. The latter term is crass and hard to say. Poor slang branding in a crowded lingual market, if you ask me.
That. And don't be a grin fucker. Tell people when you think they're full of it. Politely. Respectfully. But tell them.
