Justice League Doom/Funny

After Green Lantern saves Batman:

Green Lantern: That's three you owe me.
Batman: We keeping score?
Green Lantern: Not literally.
Batman: Because if we are, it's 8 to 7, my favor.

Also:

Superman: Maybe I can move the earth out of the way.
Batman: Even if I had a week, I couldn't finish explaining why that wouldn't work.

Most of The Flash's dialogue:

The Flash: You never asked me how my wrist was healing.
Mirror Master: Fine, how's your...?
The Flash: (punches him out cold) Surprisingly fast.

- Also

Batman: I'm right behind you.
Flash: Like you have a choice.

Alfred's sarcasm. That is all.
Hal Jordan also gave off some funny lines.

Green Lantern: All right, now come the warning shots. Give up? Please say no.
Ten: You'll never catch me, Lantern.
Green Lantern: Lots of women say that.

- Makes it even more funny since it's Castle saying that =)
