The Dynamic Duo are trapped in a giant echo chamber with the sound of water dripping amplified 10,000 times. With them out of the way, Catwoman demands $22,440,000 to return Chad and Jeremy's voices, stolen by her electronic voice eraser! Batman's only clue to her whereabouts is a strange sound in the background noise of the ransom tape.
Robin: Wow. I think I'll be hard of hearing for a while.
Robin: I said, wow, I think I'll be hard of hearing for awhile!
Batman: You'll have to speak a little louder, Robin. I think I'll be hard of hearing for a while!
Batman: All right, Belgoody, tell me everything.
Benton Belgoody: Everything? Well, I--I was born in Youngstown of poor but honest parents...
Batman: Come off it, Belgoody. You're pulling my boot!
Batman: We must stay here and restore order. With 5,000 screaming teenagers, someone is liable to get hurt. Citizens! Citizens! Hi, kids!
Batman: By this time, Sir Sterling, you're aware of the serious tragedy affecting your country's most popular export?
Sir Sterling Habits: Have we stopped making those small sports cars?
Robin: We're referring to Chad and Jeremy.
Sir Sterling Habits: Oh, yes, those blighters. Can't understand a word they say. Why can't the English learn to speak?
Robin: Don Ho! What are you doing here?
Don Ho: Well, I came back to get some land we lost back in Hawaii.
Batman: And to do a little singing here in Gotham, I hope.
Don Ho: And I brought my most important prop along. It's gotten me as far as your Bat-Ropes have gotten you. Hey, I think I'll introduce Bat-Ropes in Hawaii. Pick coconuts more easy that way.
