Teal'c and Col. O'Neill in “Unfinished Business”

Col. O'Neill?

[imitating Desi Arnaz] Lucy, I'm home!

I am not Lucy.

I know that. It's a reference to an old TV—never mind, open the door.

I will summon the doctor.

No, come on. I'm fine. I'm back to being myself. Just open up.

I cannot be certain that you are back to being yourself. You referred to me as "Lucy."
