The Batman, Season 1

The Joker:
[mutters to himself in his cell, until Batman appears] The Batman! What if I hadn't been decent?

Batman:
You're never decent, Joker. Why bother adding a stand-in to your card collection instead of me?

The Joker:
[Laughs] To drive you batty, of course. And look, it's working.

Batman:
[Grabs Joker] Answers, Joker.

The Joker:
Do you really think I'd send a flunky to eliminate my favorite sparring partner? I reserve that pleasure for me alone.

Batman:
Then why -

The Joker:
Because I miss your company, Batman. [Batman pushes Joker aside] We're two sides of the same card. After all, you knew where I'd send my look-a-like to find you. And I knew all along that if I left a trail of breadcrumbs, you'd gobble them up!

Batman:
Joker, you're not making sense. Why convince an orderly to do your dirty work when you could just have him unlock your cell?

The Joker:
Because you've always been my ace, Batman. My ace in the hole! [Laughs and pulls out two sticks and plays a tune with no notes]

Batman:
What?

[Joker blows out green Joker gas at Batman's face, causing him to collapse]

The Joker:
[Cackles] I don't need you in my card collection. I never play with a full deck! [Laughs]
