Batman: The Animated Series, Season 1

Riddler:
Ask me no questions, I'll tell you no tales.

Batman:
Another riddle, Nygma?

[Four quarters and a single penny emerge from the return change chute]

Riddler:
It all makes sense when you add it up!

[In the Batmobile]

Alfred:
Four quarters and a penny, sir?

Batman:
Penny... Penny... Cent... Red cent... Copper. It's made of copper.

Alfred:
And "copper" is another word for a policeman.

Batman:
And "no tails" would be heads. Police head... Quarters!

Alfred:
Police Headquarters. Bravo, sir! It does make "cents" when you add it up!
