Does Adam West-era Batman ever mention his parents?

Question

With the camp and saccharine kid-friendliness of 60's Batman, I'm legitimately curious if they even had the ability to mention that a character was murdered, even if it's off-screen and decades before the start of the show.

Answer 1

Yes, in the very first episode

When approving some Wayne Foundation spending, Bruce remarks:

Bruce: My resources are behind you... in full.

Harris: You're a real champion, Mr. Wayne.

Female visitor: Indeed you are.

Bruce: Don't mention it, Mr. Harris. Perhaps if there had been anti-crime centers of the type you now propose when my parents were murdered by dastardly criminals...

There's another mention later in the episode, when Bruce is contemplating having to give up his crime-fighting identity in the face of a wrongful arrest suit from the Riddler:

Alfred: A million dollars...

Bruce: It's not the money, Alfred, it's the idea of it: my identity revealed, my value as a secret crime-fighter ended, everything I've trained myself for since my parents were murdered, in the ash-can.
