- Batman: Meantime, let's ponder the crooks motive.
- Chief O'Hara: A hundred-thousand smackers, that's the motive!
- Aunt Harriet: [gazing at the Bat Signal up in the sky] Mercy alive, whoever that unknown Batman is, I hope he sees the signal...
- Bruce Wayne: Ah!

- Bruce Wayne: Great heavens, what a fool I am. Isn't today Wednesday, Alfred?
- Alfred: Indeed, sir.
- Bruce Wayne: Wednesday night, Gotham Town Hall. We have tickets to that lecture on Latin American affairs.
- Dick Grayson: [snapping his fingers] Holy Venezuela, you're right!
- Commissioner Gordon: The same strange pattern every year; precisely a hundred thousand each April first.
- Chief O'Hara: Glory be! I've got it: it's to pay his income taxes!
- Batman: A loyal tax payer stooping to criminal methods?
- Chief O'Hara: Oh, sure, ah, whe - when you put it that way.
- [looking down embarrassed]
- Commissioner Gordon: I fear you're growing the cynical, Chief O'Hara; the notion of a faithful tax payer robbing a bank is clearly ridiculous.
