Mm, true. That's a totally different story, though- the janitor who has a REALLY bad day at work cleaning up alien slime which turns out to be toxic/hallucinogenic, and he nearly dies before Janet can come up with a cure. And then he can't complain about it to his family or his friends when he goes home because they don't have security clearance. :)

So, I've been brainstorming with a friend, who suggested that maybe there was an alien artifact that was actually a prison for semi-corporeal beings, and some of the prisoners got released when SG-1 touched it. Then, the aliens possessed them either to escape offworld or to live out their lives somewhere else on earth. So it was probably either Daniel's or Sam's fault, which means that one or both of them is possessed. And I kind of want Teal'c to be possessed too, just because it never happens to him, but I'm not sure if it can be justified. The possessed ones would probably be accusing the non-possessed ones, but one of the non-possessed ones could think that the other non-possessed one was acting suspiciously too. Like mafia.
