This is a sport??

Darrel is watching the Masters downstairs. It's a big golf tournament. It seems like there's a Big Golf Tournament on TV every other weekend in spring, but I digress. Why exactly is golf classified as a sport?? I'm with Rosie O'Donnell on this one: there's no defense. Also, unless you are walking from hole to hole in the hot sun, there is no sweating or exertion.

Along those lines, why is poker regularly shown on the various incarnations of ESPN?? (Or the Travel Channel, for that matter?) Poker certainly cannot be considered a sport by anyone's definition. An activity, a highly enjoyable one (sometimes), sure, but sport? Nope.
