In the scene where Harris is riding the stationary bicycle, in the background, there is a woman being taken away by paramedics. I don't know why though. Can anyone figure out why? Also, what little things did you notice?
At the beginning of the scene, there is a man juggling chainsaws. If you listen to the background noises, you'll hear him start to scream, as if he caught one the wrong way. I have always thought it was him being taken away by the paramedics.
The whole idea is the nonchalance (or self-absorbtion) of Los Angelenos - even someone dying a few feet away doesn't faze them.
If you look closely, you can see as she is being coverd with sheet and taken away some guy comes running in to jump on the exercise machine (think it's a rowing machine, can't remember) she just recently "vacated". Too funny!
