So simple yet so effective:
"Who are you?!"
"I don't know..."
And, of course:
"Looks like I came just in time."
"Few minutes ago wouldn't have been so bad either."
"What are you gonna do?"
Sandman's final speech (here's what I remember):
"I didn't have any choice. My daughter was dying. I told your uncle that I only wanted the car. He told me, 'You don't want to do this. Why don't you just put down the gun and go home?' I realize now that he was only trying to help me. I saw my partner running with the cash...*bang*...there's been a lot of nights where I wish I could take back what I've done. I never meant to hurt your family. I'm not asking for forgiveness...I just want you to understand. All that's left of me....is my daughter."
"I forgive you."
Why hasn't anyone mentioned?:
"Tha' brutaliti' of 't...it's...almost....too hard to watch."
Some assorted Harry/Bernard moments:
"Do I have any girlfriends? Hey, Bernard, do I have any girlfriends?"
"Not that I know of, sir..."
"Bernard, we're having a guest."
"A guest, sir?"
"Yes."
"A GUEST guest, sir?"
"Yes...will you just get some food?"
I could go on all day...
