*During the shooting of season four's "Window of Opportunity" we realized that we were going to be short, meaning, we weren't going to have enough film to fill the hour. Rob Cooper and I had often joked about driving golf balls through the stargate as a "long drive" competition, and suggested the scene on the fly. I even tried it once the tee was set up, with two shiny sets of golf clubs our set Decorator Mark Davidson got from Calloway. In short order, several of the crew were taking turns hammering drives through the stargate, until somebody accidentally hit it with a nasty slice, and we realized we had to knock it off before somebody smashed a Chevron.
