Batman: The Animated Series, Season One

(Alfred and Batman are in the Batcave examining one of the Joker's fish, when all of a sudden, a TV commercial comes on)

Harley Quinn:
[singing] They're finny and funny and oh so delish! They're joyful and jolly Joker fish!

[Fade to a generic dining room, featuring two of the Joker's henchmen sitting at the table, dressed as small children, with Harley wearing an apron which reads "Kiss the Cook"]

Narrator (Joker):
Say, Mom. Wondering what to feed the family tonight?

Harley:
What'll I feed the family tonight?

[In walks the Joker, dressed as the Gorton's Fisherman]

Joker:
[pirate's accent] Arrr! Try me famous Joker fish! There's Smiling Smelt! Giggling Grouper! And Happy Haddock!

Alfred:
[to Batman] This could cause a stampede to pork!

Joker:
Yummy-yum-yum! [takes a forkful of fish and holds it in front of Harley, who obviously doesn't like fish] Eat it!

Harley:
Ummm, Mistah J?... I have this little...problem with fish--

[Joker shoves the forkful of fish into Harley's mouth]

Harley:
[visibly disgusted] Yummy-yum-yum... [quickly runs out of frame]

Joker:
Yes, friends, that's Joker fish! [Harley loudly retches off-camera] Tasty! Tempting! And of course...

Henchmen:
[flatly] Naturally low in cholesterol.

Joker:
Coming to your local store! [menacingly] Just as soon as that nasty ol' Mr. G. Carl Francis decides to give me my legal cut of the profits!
