在《蝙蝠侠6黑暗骑士》中，希斯·莱杰扮演的小丑有一些非常经典和深刻的台词。以下是一些被广泛引用的台词：

“Can't rely on anyone these days, you gotta do anything yourself.”

“Oh, sing the blackface, sing the whiteface program from the beginning. Don't start to hit, the victim will be dizzy, your continuous attack will have no effect.”

“Why so serious？!”

“I believe… whatever doesn’t kill you simply makes you… stranger.”

“Let’s not blow this out of proportion.”

“I’m like a dog chasing cars. I wouldn’t know what to do if I caught one… I’d just do things.”

“Face up to it, boy. It's over.”

“You’re just a freak – like me. They need you right now. When they don’t… they’ll cast you out. Like a leper.”

“It’s a funny world we live in, speaking of which, you wanna know how I got these scars？”

这些台词不仅展示了小丑角色的复杂性和深度，也体现了希斯·莱杰对这一角色的精湛诠释。
