Dr. Jackson and Col. O'Neill in “Unfinished Business”

I always seem to be saying goodbye to you.

Yeah, I noticed that. Why don't you stick around for a while?

I can't, really.

You just did.

Special occasion.

Christmas?

No.

Groundhog Day?

[trying not to smile] Nooo.

I've got my journey, you got yours?

Something like that, yeah.
