Nabiki: Is dating girls all you ever think about, Kuno?
Kuno: Fear not, Nabiki. I have no intention of asking you out.
Nabiki: And for that, I am grateful.

Kuno: Keep in mind that a man of my position is not accustomed to asking favours.
I would take it ill indeed if you took me lightly in this, Nabiki Tendo.
Nabiki: Yeah, yeah, yeah. So spill it, already...

(Nabiki is selling photos of the "pig-tailed girl" to Kuno.)
Kuno: I protest! The heavens themselves would weep at a thousand yen per shot!
Nabiki: So, you don't want them?
Kuno: I'll take them all!

Kuno: Powerful and lovely Akane, like Diana on the hunt...
Pig-tailed girl, bursting with healthy beauty...
They are so dear to me that I cannot bear to part with them.
You call it deceit that I would date with them both?
'Thus, do quick, bright things come to confusion.'
Nabiki: Not at all, Kuno-baby. That's what I'd call two-timing, wouldn't you?

Nabiki: It's a hundred yen per pair, Kuno-baby.
We're not in and you're already passed out.

(Kuno and Nabiki are in a sinking rowboat.)
Kuno: Very well, Nabiki Tendo. I shall pay you 5000 yen to depart the craft.
Nabiki: Make it 10,000 yen.
(Kuno is accidently knocked off the boat.)
Nabiki: Golly, Kuno-baby. Who knew you were so cheap?

Kuno: To brazenly fondle the tender pulchritude of a
female instuctor in the broad light of day-- Ranma Saotome!
You are a cretin! A cretin, I say!
Nabiki: Kuno, try not to sound so envious.

(Kuno has just sent a talking bust of himself to Akane and Ranma.)
Kuno's voice: Akane Tendo... Pig-tailed girl. Greetings! I regret
to inform you that I, Tatewaki Kuno, will be absent from school
for the next few days. Feel feel to bestow upon this replica
the usual loving kisses, tender caresses, etc. etc. etc. etc...
(Akane and Ranma stomp on the bust in disgust.)
Ranma: Geez, ain't it dead yet?
Nabiki: Kuno-baby has such bad taste.

Kuno can even make the mundane sound eloquent...

"Hmph. Would that I would share my good fortune with you, but
in concern of your well-being, I must, in good conscience,
refrain. The effect of rich, European cuisine upon
an unrefined palette is unsalutary, at best."
