What's your all-time favourite quote from an anime or manga? 
Mine probably has to be from the One Piece Enies Lobby arc:
Random marine: "Franky's ass is inflating!"
I'd love to see the expression of the people who aren't up to that part yet. :happy:
This has been done before.
But here's mine:
Saiyuki:
Ukoku Sanzo: "Say you're the moon, and I'm the night. Which one of us swallows the other?"
I can only think of two at the moment. I'll probably come up with more later.
Yuki Judai. If you want to defeat evil, you must become evil. In this cruel world of deceits, you must rule by power!
-Supreme King (Yugioh GX)
If I do this, I can stop the rebellion", "if I do that, I can stop the rebellion"… Open your eyes, princess! Your zealous idealism disgusts me! Ideals can only be spoken by those powerful enough to carry them out. And that excludes you!
Bari, "Give Me the book"
Kiyo, "Like I'll listen to a crap candy in a blue suit"
Bari, "Tschu!" "You must really want to die, Ningen Sucker"
Negima! (the anime)
Right after Negi sneezes and gets a glimpse of Asuna's bear panties:
"THAT'S THE LAST BEAR YOU'LL EVER SEE!"
"If God himself stands in your way, kill him and follow your own calling!"
Deshwitat Rudbich, Rebirth (close enough to a manga to count) book 5, pg. 62.
Cowboy Bebop has some great ones:
Vicious: "There is nothing in this world to believe in."
Spike: "My left eye sees the past."
Julia: "And your right?"
Spike: "…"
Julia: "This is... a dream, right?"
Spike: "Yeah... a nightmare."
Spike: "Bang."
