There was another Stargate: SG-1 episode (don't know which one... I've only seen Seasons 1-3) where Jack and Teal'c go over to Sam's place and bring a copy of Star Wars. Jack says something like "Teal'c loves this movie. He's seen it, what... eight times?" Teal'c replies "Nine times." I saw that clip on Stargate: SG-1 -- The Lowdown right before the Season Seven premiere.
