22 Greatest Moments In Scott Snyder's Batman Comics
7. Batman #37: "Hi"
This is a pitch-perfect Joker moment. Everything that's great about the character is captured with this one panel, and with this one word. Joker has invaded Gordon’s home, and he’s been threatening him for a couple of pages now, when suddenly Joker pauses to say, “Hi.”
I can't explain what is so hilarious about this. It’s like he doesn’t know how to properly hold a conversation. Anyway, his simultaneous playfulness and axe-wielding menace make this an enduring Joker moment.
