"Oh, jeez! Where'd you get those horns?! I want some of those!"

This dog is never going to get to play with that deer if he keeps up that attitude. He needs to play a little harder to get. And then he's got to "neg" that deer. Something like, "Those horns make it look like you're overcompensating for something." It doesn't seem like it would work, but it does. Believe you me.
