Robin is in a cage in The Jokers lair.
ROBIN: Holy imprisonment Batman, get me out of here!
JOKER: The big ol' bat won't be getting you out of this one... You queer! I have rigged every single doorway with mother fucking joker bombs!
Batman climbs in through the window.
JOKER: OH SHIT!
BATMAN: Looks like I have seen through your... SHADY plot!
ROBIN: Really Batman?
BATMAN: You try to think of a clever window oneliner... You queer!
ROBIN: Ok, how about "I have seen through you transparent plot?"
BATMAN: That's just mine with transparent instead of shady!
ROBIN: The window doesn't even have shades... It makes no since whatsoever.
The Jokers legs are seen as he is escaping through the window.
BATMAN: You let him get away!
ROBIN: Me? I'm stuck in this cage. You are such a PANE! See? Not that hard.
