Tiger Woods, Y'all

I know, Tiger Woods is one of the most amazing, successful, impressive athletes in the world, but whenever he's on the course, unless he's on the 18th hole and about to win another million, doesn't he have a pained look like he's pinching peach seeds or something? Poor guy always looks like he's completely tortured! I guess that is the sign of a fierce competitor, but good golly, enjoy it already!
