There was one scene in "Coup D'Etat" that turned me into a Lorne fangirl:

SHEPPARD: Major. Boys.
LORNE: Colonel.
SHEPPARD: Way to be alive.
LORNE: Thanks, sir! So, uh, have you come to rescue us?
SHEPPARD: Well, until about a moment ago I thought were dead, but now that I see you
speaking and breathing, yeah, I’m thinkin’ about it.
LORNE: Well, good! Let me know if there’s anything we can do to help, huh?

You can tell that Lorne's had such a bad day, yet he still can't resist the martini-dry humor!
