"Did you hear the rumors"

"what, that Harley used to be a dude"

laughed my ass off on that one. What about your favorite lines?

When Batman quotes Catwoman,

"I think I broke a nail"

Sounds so weird coming from Batman.

I'm batman.

I don't remember it exactly but Batman just straight up answered someone "No." It made me laugh at the time.

Don't remember it directly but (SPOILERS) When Batman says, "You know, after all that you have done I still would have saved you." to joker. Shat my pants.

The interplay between Batman and Alfred towards the end of the game was pretty great, it was interesting seeing the interplay, and Batman sounded suitably messed up.

Whan he saved that news reporter and asks "You a fan?" -No.

"I'm Batman."

When he punched the shark. There was no dialogue but it was implied.

IT'S THE BAT!!!

"Solomon Grundy, Born on a Monday, christened on Tuesday..."

forget the exact lines but when someone tells batman there are mines in the other room and ask if he is worried and batman just responds with "do i look worried?" that made me lol.

"Face or legs? Which do you want me to break first?"

I'm batman.

I'm batman.

"Ring, ring, ring, somebody answer the damn phone already" - there's no phone ringing.

"Two guns, bitch!"

This. Fucking awesome moment. When of my favorite lines of all time

I liked when the guards were making sexual jokes about Harley like they were gonna ride her and stuff after Joker dies. lol

When the lady asks Batman if the mines will stop him, and he says, "Do I look worried?". Awesome.

Ridder informant: please, no! I'll tell you everything!

Batman: there was never a doubt in my mind.

*elbow to the face, tosses him aside like a used candy wrapper*

Oracle: "Wonder tower just exploded!"

Batman (after jumping out of exploding Wonder Tower): "I noticed."

The part where Two-Face says bitch

The random dialogue between the prisoners is pretty great, the references to Lost were pretty unexpected so I liked those a lot

The final scene of the game

Gordon: What the hell happened in there? Batman? What happened?

Also not from the game but I love it.

I'll tell you anything! Just please don't hurt me!

Alright *smash thugs head into brick wall*

Riddler items added to map!

Haha, there's a really funny comment one of the thug makes, it goes something like "Man, it's been ages since I updated my status, how are people gonna know what I - oh, yeah, I've been locked up, freezing my ass off!"

"Besides, it's not like you have a girl to save. OOOOH. Too soon?" -Joker

I remember that, but I also cannot place exactly what the context was. I laughed pretty hard because of the context, I remember that.

@DrPockets000:

I found it :D

I really like the LOST reference in the game as well.

When some thug did an impression of the Joker and Harley. I wanna know who that VA is.  
 
Edit: here it is 
  

"I only just got the last guy's blood off my face" is pretty great. Actually, any of the stuff that he says to the Riddler informants is pretty great.

The voicemails from Joker during the credits are great too, especially when he sings.
