Robin: What's botherin' you?
Batman: Harrison's safety. The Wizard must have heard that broadcast - perhaps he even inspired it.
Robin: Harrison's decision really must have knocked the props out from under his blackmail scheme.

Robin: Batman and Robin might.

Batman: Run the usual test for invisible ink. I'll change and go entertain Vicki.
Robin: You better be careful. I think she's beginning to get wise that Batman and Bruce Wayne are the same.
Batman: Well, if she gets too close, we know how to throw her off the trail.
