Batman speech marks

The plane lifted off into the clouds. "Hey, are you up for another top secret hero mission to defeat the Joker? Said Batman, as the plane zoomed away. "Oh i'm down to stop that clown." Said Robin while peering round the chair. " But I don't want to make my other dad - Bruce Wayne, angry. Do you think we'll be done before my bedtime?" Asked Robin. "Bedtime!" Screamed Batman angrily. "Batman's life lesson number 2. Vigilantes don't have bedtimes." Said Batman, leaning back in his chair. "Yes!" Exclaimed Robin happily. "So - what's the vigilante policy on cookies?" He asked hopefully.... "Unlimited!"
