^^^^ LOL!
It's not a good sign that the guy knows all the rhetoric, talks the talk but when the rubber hits the road, it's all about the noodling.
The best you can hope for is gradual progress. If you can somehow coax that out of him, there's hope. (I say this as a recovering noodle-aholic, who had to work up whatever tastiness I have pretty much from scratch.)
But if he nods in agreement then doesn't change, or if he makes a big stink, just get out of there. He'll be having the same conversations, same arguments, 40 years from now.
