We're going to try not to complain because any excuse to watch Ryan on TV is good enough!

Ryan sat down with David Letterman to chat before they finally got around to showing a clip of Ryan in Crazy, Stupid, Love.

"What are we going to see here, Ryan?" David asked.

"Well, I think that they are gratuitously using a clip of me with my clothes off. So, if you want to just do that..." Ryan said.

And that's exactly what the clip did!

But before then, Ryan shared a very funny story about how his sister was hit on by Peter. The handsome actor had attended his first Oscar nomination with his sister and claims she was hit on by Peter!

"Peter. Big fan," he recalls telling the star. "You're a legend. But you gotta get your hand off my sister."
