Found this spot in my archives. I remember when I first saw this I thought for sure it was done with special effects. Yeah, that ball was just inserted and made to look pretty seamless. Wrong!
The story goes Tiger was just fooling around in between takes of shooting another Nike spot when the director and crew noticed what he was doing and decided to roll the camera. The rest, as the say, is history.
For those of you who play golf I'm sure you've seen plenty of people attempt to emulate this skill. I myself have mastered the bounce for about 3 or 4 times. Forget behind the back and between the legs. If I recall, this spot was the result of 3 takes this being the third. Amazing!
