Everything he did showed it. Including drinking copious amounts of water when he was nervous. Probably trying to figure out how to lie his way out of a headlock. It was a thing to behold. He tried laughing like Joe and that was precious, but it made him look like a jerk rather than a what Biden's laugh did. When Biden laughed it was like "can you believe this clown, what is this his 10th lie, I've lost track". Ryan knew he was lying and Biden showed a whole lot of people where the lies fail.

look confident. Ryan didn't look uncomfortable to me.
