Star Trek: Deep Space Nine, Season 6

[Jadzia and Worf have just announced that they are trying to have a baby.]

Jadzia Dax:
Well, you two are awfully quiet.

Julian Bashir:
Uh, look, um, I don't want to dampen your spirits, Jadzia, but I told you before you were married that, from a medical point-of-view, it wouldn't be easy for a Trill and a Klingon to have a child.

Quark:
And I'm worried the kid'll end up looking like his father.

Jadzia:
[offended] Well, I hope she does. [makes a face and walks off in a huff]

Bashir:
A baby.

Quark:
It's bad enough she married that Klingon psychopath.

Bashir:
A baby. Do you have any idea what that means?

Quark:
That their marriage is gonna last. A lot longer than we thought.
