The Dark Knight
- "Why so serious?"
- Simple: Why are you being so serious?
- "People reveal their true colors moments before they die, so I guess, I knew your friends better than you ever did."
- Simple: People show what they are really like when they are dying. So I know what your friends are really like.
- What it means: I killed your friends and so I know them better than you.
- "Evening, commissioner."
- Simple: Hello.
- [about Rachel] Let her go...
The Joker: Ooh, very poor choice of words…(laughs)
- What it means: The Joker is holding Rachel over a long drop. Batman says "let her go" meaning "put her down". However, "let her go" can also mean "drop her." So The Joker laughs and drops Rachel.
- "Welcome to a world without rules."
- Simple: Welcome to a world where there are no rules.
