Quote from Lorelai in You Jump, I Jump, Jack
Emily: You have a gentleman friend of significance. Lorelai: Rhett is my gentleman friend, yes. Emily: So it's only proper that you introduce him to your mother. Unless he's insignificant. I don't want to meet a passing ship. That's a waste of my time. Is Luke a passing ship? Is he insignificant? Lorelai: No, he's not.
