We've had a blast watching everyone in the office try this - everyone tries it three or so times, just to make sure I imagine. Except it doesn't work on me, so I had to do it more just to prove it. I am no brain expert but I am guessing it must have something to do with my ambidexterity - I would hate to leave one side of my brain out of a situation!
