TKJ has a few.
"All it takes is one bad day to reduce the sanest man alive to lunacy. That's how far the world is from where I am. Just one bad day. You had a bad day once. Am I right? You had a bad day and everything changed" - Joker
"Sometimes I remember it one way, sometimes another. If I’m going to have a past, I prefer it to be multiple choice." - Joker
"Hello. I came to talk. I've been thinking lately. About you and me. About what's going to happen to us in the end. We're going to kill each other, aren't we? Perhaps you'll kill me. Perhaps I'll kill you. Perhaps sooner. Perhaps later." -Bats
and on and on.
there are also these:
"Look at us, Clark. I've become a political liability, and you... you're a joke." - Batman
(to Superman) "Everyone looks up to you. They listen to you. If you tell them to fight, they'll fight. But they need to be inspired. And let's face it "Superman"...the last time you really inspired anyone -- was when you were dead." - Batman, Infinite Crisis
Dear, sweet Harley Kwink...I'm madly in love with you. Marry me! We can go to Canadia. Or Boston or something. It'll be grand...You know the cookies are a given. They are ALWAYS a given. You could dump me tomorrow and you'd still get the cookies. Boston..shit, wherever dyke weddings were legalized. And where better to rub their little piggie noses in how bad they suck than right on their doorstep? What are they gonna do? Be jealous of you? Stare furiously at your tah-tahs? Not willingly give you cookies, but instead begrudgingly give you their cookies? Woman, time to wake up to the powers you wield - Uschi
