I always liked the one is season 10 where Valas father came to the base, and by this time they knew they weren't getting season 11.
During one scene, they are talking about how the sgc is facing possible shutdown, and Jayce asks something along the line of "why would they suddenly decide to stop supporting you?" and Bill yells "Eureka!" from the other side of the room.
For those who don't know, the SciFi channel basically abandoned Stargate in favor of Eureka, trying to chase that "people want future tech stuff" vibe I guess.
