Note to Self: You are easily amused

So I'm doing, er, research, yeah, watching the SGA episode "Inferno" (the one where they're in the middle of the Volcano and McKay's trying to get the Orion functional while trying to flirt with the blonde scientist lady).   I never noticed it before, but in the scene towards the end, while he's trying to get the shields up and the volcano's about to go, he's under a console and freaks out because he bent his fingernail backwards, and when he shows everyone the massive injury, he totally flips them all off.
