T-Rex: The Joker, who loved pulling pranks, finally had one pulled on him! He'd been transformed...

T-Rex: ...INTO A DOG.

T-Rex: Commissioner Gordon would've found this FRANKLY ADORABLE, except he'd been turned into a dog too. In fact, all of Gotham City was now dogs!!
Dromiceiomimus: Including Batman?
T-Rex: INCLUDING BATMAN.
Dromiceiomimus: So did Batman's car shrink down to dog sizes too, or...?
T-Rex: No, that's ridiculous. Organics only!!

Utahraptor: So Batdog drove a regular sized car.
T-Rex: Yes. IS THAT NOT ADORABLE?

T-Rex: Look, all I'm saying is: these characters have been around for generations. Sometimes you gotta mix things up, and the easiest BUT ALSO THE BEST way to do that is to make everyone dogs. It worked for Paradise Lost!
Utahraptor: Huh?

Narrator: LATER:
T-Rex: Yes, hello, it has come to my attention that I have been reading a brilliantly vandalized version of Paradise Lost
