Is that Sergio Garcia the golfer?

I had to watch it several times to figure out his technique. His right hand is held upright, as expected. What's unexpected is that he turns his left hand practically upside down so his (left) middle finger is bracing the outer end of the (right hand's) cork while his (left) thumb is on the inner end of the cork. Then his right hand's middle finger and thumb picks up the left hand's cork normally.

I didn't have wine corks so I could only try it out with clothes pins. I had some difficulty because the clothes pins are longer than corks, but it's do-able.

Sorcery!!! Burn him!!!
