Batman: The Animated Series1992

The Joker:
If this lunch meat figured out where we are, Batman won't be far behind. And why spoil my sharky's appetite, when I can feed him bigger fish?

Harley Quinn:
Eyugh! Again with the fish, I *hate* fish!

[off Joker's glare]

Harley Quinn:
Uh, no offense, Mr. J.

The Joker:
Poor Harley. This entire caper's been really rough on you, hasn't it?

Harley Quinn:
Uh-huh.

The Joker:
Cheer up! You can be my very own little mermaid.

[Harley squeals with joy, then Joker pulls a giant rubber fish head over her, and laughs]

Harley Quinn:
You're really sick, you know that, boss?

The Joker:
Mmm-hmmm.
