Madness is like gravity. All you need is a little push.
瘋狂就像是地心引力一樣。你只需要輕輕推一下就夠了。
I'm like a dog chasing cars. I wouldn't know what to do with it if I caught one!
我就像隻追著車跑的狗一樣。就算追到了那部車我也不知道該怎麼辦才好！
Why so serious-ah?
幹嘛這麼認真啊？
Slaughter is the best medicine. (Original phrase: Laughter is the best medicine. Joker added a big, red S in front.)
屠殺是最好的良藥。(原句：微笑是最好的良藥。小丑在前面用紅筆加了個大大的S。)
(Lighting a match, preparing to burn the pile of bills) You see, I am a guy with a simple taste. I enjoy dynamite, gunpowder, and gasoline. And do you know what they have in common? They are cheap! And you, all you care about is money!
(一邊點火柴準備把身後整疊鈔票燒掉) 這樣說吧，我是個品味單純的人。我只喜歡炸藥，火藥，和汽油。知道它們有什麼共同點嗎？它們都很便宜！而你，你就只關心錢而已！
(In the interogation room) Do you want to know why I use a knife? You see, guns are too fast. You can't savor all the little......emotions. In their last moments, people show you what they're really like. So, in a sense, I know your friends better than you did. Would you like to know which of them were coward?
(審問室裡) 你想不想知道我為什麼用刀子？這樣說吧，槍的速度太快了。讓你無法細細品味那些……情緒。在一個人生命的最後幾分鐘裡，他會露出他真正的本性。所以呢，某方面來說，我比你還了解你朋友喔。你想不想知道你朋友中哪一些是懦夫呢？

It's all part of the plan!
一切都在計劃之中！
C'mon, hit me, hit me, hit me, hit me, hit me, hit me!
來吧，來撞我，來撞我，來撞我，來撞我，來撞我，來撞我啊！
I like that!
我喜歡！
