anecdotally, i had a professor (if you're reading this, hi) who would wink in conversation at exactly the right point to add a little "isn't the world a funny place" comedy to whatever he was saying... wasn't clear if intentional or a tic for when he thought he had said something clever. I noticed that habit to have transferred to me for a while after, though I think now it's faded.

As a presales engineer, I worked with a winky sales rep for a year or two and absolutely picked up this winky habit.
