In The Shawshank Redemption (1994), while resurfacing roof of the license-plate factor, prisoner Andy overhears the captain of the guards, Byron Hadley, complaining about being taxed on an inheritance and offers to help him shelter the money legally:
Andy: Mr. Hadley...do you trust your wife?
Hadley: Oh, that's funny. You're gonna look funnier sucking my dick with no teeth.
Andy: I mean, do you think she'd go behind your back, try to hamstring you?
Hadley: That's it. Step aside, Mert. This fucker's having an accident.
Here Andy clearly provoking Hadley in this scene.
What's the point of Andy's provocation before giving him tax advice?
