Behind the Scenes of The Simpsons

"Invitations to the table read are considered among the hottest tickets in Hollywood, and each visitor has an assigned seat. Celebrities, usually with children in tow, are a fixture. It takes about 40 minutes to run through an episode that will run 22 minutes and 30 seconds (plus commercials) when it airs next season. After the session, there is applause and stretching. Groening and most cast members linger to chat, autograph the scripts and pose for snapshots."
