to be perfectly honest, i don't really enjoy watching any of them. i tried to get into it over and over as a kid. i even played most of them, with some limited success. however, i spend pretty much zero hours per week watching ball throwing / ball hitting. when ball throwing preempts the nightly news, it annoys the **** out of me. i like playing golf, though.
i watch one sporting event each year, and that's the superbowl. i do it as an excuse to order pizza and swill beer. also, watching the superbowl is the minimum requirement for a guy card. if you don't at least do that, they knock on your door, take the card back, and remove your testicles.
i have been an extra in two popular sports movies, though. THAT was fun and entertaining.
