Actually just a scene, but it really worked.
Elaine is is J. Peterman’s office helping him record a series of messages to automatically play over the office PA system in the event of an emergency- “Fire! Prometheus’s gift has turned against it’s masters” You get the idea. The gag is that the messages gradually become for more and more ridiculous and unlikely events. Tsunami, nuclear war, etc. The last message is for if they discover that they are merely characters in an fictional world. “Don’t despair, for as the Bard said, ‘All life’s a Stage, and we are merely players’” Elaine then interrupts him and asks if they all turn out to be fictional, isn’t Shakespeare fictional, too?
Just thought I’d share.
