Behind the scenes at "Fashion Rocks"

Because "Fashion Rocks" is more a TV show than an actual concert experience, there's a lot of downtime between performances, meaning there are lots of entertainment that won't make it on the air in the two-hour special tonight at 9 on CBS.
BEST JOKE YOU WILL PROBABLY SEE: Host Jeremy Piven's bit on how he has always been an inspiration for fashion designers. With childhood pics, he showed how his feathered hair and puka-shell necklace inspired looks from Kristy McNichol and Benjamin McKenzie from the "O.C." and how he one rocked the "jullet," a Jewish mullet.
BEST JOKE YOU MAY OR MAY NOT SEE: Denis Leary setting the scene -- "Backstage is full of rock stars and models, so there's plenty of food, but we're running out of alcohol and cigarettes."
BEST JOKE YOU WON'T SEE: Greg Giraldo discussing Rolling Stone's naming of President George W. Bush as "Worst President Ever." "Is that even possible? Remember the president of the Selena Fan Club? She was pretty bad. She actually shot Selena. That's bad for a president. That's more of a vice president thing to do."
