We spend a lot of time on the internet. And for the most part it's just grumpy cat gifs and funny dog memes.
But then sometimes you can strike gold such as this exceptional piece of work by artist Butcher Billy.
Entitled the Nolan x Burton Experiment, it's a mash up of the different versions of Batman by both directors.
In the images below both Christian Bale's and Michael Keaton's Batman (Batmen?) have been switched around. Similarly, Jack Nicholson's and Heath Ledger's Joker have been given the face swap treatment.
