Cheerleader I: Hey, Batman, where's Robin?
Batman: [speaking through Bat-bulhorn] Attending school, just like as you are.
Cheerleader II: What school?
Batman: I can't tell you that, it might reveal his secret, true identity.
Batman: What's your name, son?
Dick Grayson: [stands up straight] Richard Grayson, sir.
Batman: Thank you, Richard. You darken the room, I'll man the projector.
Batman: [speaking through Bat-bullhorn] Boys and girls, go back to your studies. Believe me: nothing in life is free!
The Joker: [picks up phone] Hello, hello? Give me the sign.
Suzie: [on other line] How do you stop a dog from barking in July?
The Joker: Countersign: shoot him in June. Very good!
The Joker: [showing up in the school, laughs] Hello kiddies, meet the Joker!
The Joker: [Batman prepares to arrest the Joker for loitering in the school] Wrong kiddies, look up the statute, in Gotham City the crime of loitering requires the loiterer to remain in the same spot for over two minutes.
Batman: You... you jailhouse lawyer!
The Joker: Trusting little wench, aren't you?
Suzie: [stands up] I'm a crook, Joker, just like you. Now where's the payoff?
