One of my old online friends (Ron Moore's next-door neighbor, oddly enough) had a friend who worked for one of the studios (in accounting or legal, as I recall), and he swung her a trip to the Stargate set. They assumed she was somehow a studio bigwig bean-counter and wanted to impress her, so she got to spend a whole day sitting with the cast around the big mission briefing table in the stargate control room, and she said it was a blast! She said they were all hilarious and fun and extremely
nice. I was soooo jealous!
