The Joker vs. Patrick Bateman
This just came to me a few minutes ago, thought it would be interesting... hmm
Anywho, scenario 1: Takes place in hells kitchen, or the same place Patrick left the bodies. Joker has his knifes and a crowbar, Patrick has his axe and is naked so The Joker could easily be distracted.
Scenario 2: Who is crazier?
