I used to work at a regional exchange and photographers would come by on the big up or down days looking for shots. I knew what they were looking for so I put my hand over my face. Even though I was smirking I got on the front page of the SF paper.
Conan O'brien did a comedy routine a couple of weeks ago where he had three traders in his audience and they had those sad faces while he did his stand up jokes. It was very funny.
I tried to find a clip on YouTube to post but couldn't find it. I guess NBC has copyrights to the show and maybe it can't be posted.
