Batman: The Killing Joke is often praised for its dialogue and rightfully so. However, there's one quote that I never quite understood: the Joker's last gag.
I know they say a joke isn't funny if you have to explain it but I would like to understand where the humours bit comes from.
Or is this more of a metaphor of Batman and the Joker's relationship than an actual joke?
Please help.
Thanks!
I didn't find the right solution from the Internet.
