gray_wolf: LOL! I love that. I tried it myself and found better luck not trying to widen my eyes at all but simply closing one eye slightly. This was easy, as it is merely a partial wink. The tricky part is getting the other eye wide without moving the eyebrows. I found I could sort of do this with both eyes together, and then and only then endeavor to close one partially. I think I was successful (no mirror handy), but I'm sure I didn't do as brilliant a job as John Steiner did.

To be fair, though, he didn't have to hold the expression. That was just one frame in a constantly changing series of amazing facial poses.
