Some of the dialogue in TAS will live rent free in my head forever.

Batman:

I saw what happened to your wife. I'm sorry.

Mr. Freeze:

I am beyond emotions. They've been frozen dead in me.

Batman:

That suit you wear - a result of the coolant?

Mr. Freeze:

Very good; a detective to the last. I can no longer survive outside a sub-zero environment. Tonight, I mean to pay back the man who ruined my life... our lives.

Batman:

Even if you have to kill everyone in the building to do it?

Mr. Freeze:

Think of it, Batman: to never again walk on a summer's day, with the hot wind in your face and a warm hand to hold. Oh, yes. I'd kill for that.
