I have no idea if anyone has ever done a grab of this scene but I distinctly remember a shot of Dick Van Dyke, which I am pretty sure was from the old Dick Van Dyke Show, where he was on a street corner trying to avoid being noticed. He had his back to the camera and wrapped one hand across the front of his neck and around to the back of his neck, and the other hand across his torso and around to his side. From behind this gave the impression that someone was embracing him and kissing.
I have never seen this gag done by anyone else and have been unable to google it up. Anyone even remember what I am talking about?
