When Freize and Caine first meet, there is a brief flashback to the "Gunfighters" episode.
Strenlich: We ought to celebrate your birthday out here every year.
Skalany: Oh no, no more birthday parties for me, Chief. I'm thinking more along the lines of a day of mourning!
Jody: That dude looks like he's been hanging upside down in the batcave.
Skalany: Isn't that where we lost Blake once?
Blake: I heard that!
(looking at the funhouse mirrors)
Peter: Should this be our true perspective on reality?
Caine: I surely hope not!
Nicky: Do you think the babes on Waikiki will know I'm a coroner, dressed like this?
Peter: Not if you don't have Coroner's Weekly or Corpses I've Known delivered to your room.
Caine: (to Xenia) You read the cards. You seek the truth--a dangerous and a troubled path.
Xenia: Have you ever wondered if your life would be better without premonitions? If grief and pain could be strangers?
Caine: Treat them as such, as impostors, or grief can become resolution and pain can give way to joy.
Peter: I went to an opera once.
Karen: You shoot anyone?
Peter: No, not that I remember. I was asleep most of the time.
Inky: (about his height) I'm not a little person here.
Caine: You never were a little person. Your heart and your soul are of infinite size.
Caine: Whether or not we have met before, once the gauntlet is thrown down, it must be picked up.
Frieze: What gauntlet is that, sir?
Caine: The challenge of evil.
Frieze: Ohhh, that gauntlet. It would take a man of great power to accept the challenge.
Peter: It's not over till the fat lady sings, right?
Karen: (after Peter leaves) I'd just rather not hear it singing over your grave.
