The trivia item below may give away important plot points.
In the series finale, during the funeral for Amanda Woodward and Peter Burns, the entire writers' office staff are scattered among the extras in the audience, and featured prominently in several shots. The shoot took an entire day under the sun on a beach near Malibu. If you watch closely, you can see the extras in the audience gradually turn redder. Also, the "ashes" accidentally scattered at the end of the funeral were pulverized blue corn tortilla chips.
