Stargate SG-1 Easter Egg - Robert Cooper: Respected Novelist?

In this episode (season 5, "Wormhole X-Treme!"), Col. O'Neill goes to a toll booth and asks for records of everyone who
enters/exits television studio.

At the beginning of the scene as O'Neill enters the booth, the woman who keeps the records is reading a book called "Dust off that
Screenplay and Sell It!" The books author is Robert Cooper, one of the main producers/writers of the show.
