“Did he just wink?” whispered Downing.
“If not, he developed a very timely facial tic,” Caine replied.

I smiled, and you winked. I think. Perhaps you merely blink with one eye at a time.

[On the Pink Panther films] I had a scene with Peter [Sellers] in my office. He said something like, "Don't worry chief, I'll settle it," and gave me an encouraging wink. So I started winking out of nervousness, and couldn't stop. It wasn't in the script but Blake Edwards [the director] loved it. But it became a problem. I made those films for 20 years, and after 10 years they ran out of good scripts. They used to say to me, "Herbert, wink here, wink." And I said, "I'm not going to wink. You write a good scene and I won't have to wink."

Behind a frowning providence He hides a smiling face.

Maybe that's what life is... a wink of the eye and winking stars.

knowing smile on his face: What’s this mischief here?

Justice may wink a while, but see at last.
