I'm a useless winker - any attempt at a subtle/seductive closure of one eye results in what a recent observer described as "an attempt at Quasimodo without the hump".
So - a quick poll - can you wink properly (or indeed improperly)??
yeah - it really gets them going , especially when i combine it with the Spock eye brow movement as well ( i get underwear coming at me from all directions )
