Kyo Sôma: [angrily pointing at Yuki] Just like I'll beat you one of these days!
Yuki Sôma: [looking bored] Wait, wait, I think I've heard this one before!

Kyo Sôma: One of these days, I'll make you say you're sorry!
Yuki Sôma: [looking bored] I'm sorry.
Kyo Sôma: Dammit! That's not what I meant! Don't you have any shame?
Yuki Sôma: [still looking bored] Yes, I'm ashamed to be seen with you, shouting in public.
Kyo Sôma: Oh that's it! We're taking this outside!
Yuki Sôma: [still looking bored] We ARE outside, you stupid cat.

Ayame: [clasping Yuki's hands] Yuki, let's deepen the bond between us brothers!
Yuki Sôma: [annoyed] Before you can do that I'll drown you in the deepest part of that lake.
Ayame: That's right! No matter what happens we'll be together.
Yuki Sôma: I'll let you drown alone!

Momiji Sohma: Waaaahhh! Someone! Kyou's picking on me!

"Moon Prism Power MAKEUP!" -Usagi Tsukino 'sailor moon'

definitely SIT BOY by kagome from inuyasha:cool:

I love Momiji, lol. Especially the way he whines in the english dub. It's so faked, but that's what makes it hilarious.

As for mine, it's not so much a catchphrase as a random sentence.

"I... I... I have... I have ABSOLUTELY NOTHING TO DO WITH THIS STORY!" Random awesome looking skeletal guy from the beggining of Jing: King of Bandits.

Of course, immediately afterwards he gets knocked clear off the screen by an enormous land ship and is never seen again, lol.
