One interesting note from this scene - Batman and Gandalf are name-checked. It's typical for us here at Toobworld Central to accept such references as being about real people.
So, Batman... that was a given. But Gandalf! Ooh, that's exciting! As far as I'm concerned, he did exist in Earth Prime-Time... or at least in some dimension of the TV Universe, besides the Tooniverse.
Nice to see a showcase for my first Companion, Leela, among all of the companions!
