Humor-related topic.
The battlefield is a bar, and they are allowed to use all weapons available. Victory is not required all the time.
My suggestion: The Paris stabber vs. Affonso Azevedo. (with two bonus appearances)
The fight: Azevedo, who had trained capoeira, challenged the Paris stabber to a fight with a club. The stabber accepted. The fight occurs not far from the University of Paris. Azevedo first asked the stabber in a provocative way: "do you have some money?" and the Paris stabber said he did have not. The fight begins, there the Paris stabber attempts to stab Azevedo, but he does a capoeira move and dodges. He then hits the Paris stabber in the head with a club. Azevedo then hits a person in the head thinking that he's the Paris stabber. The Paris stabber, furious, climbed on top of a table outside a café in a street, and calls Azevedo in a provocative way, and then stabs Azevedo in the arm. Azevedo then kicks the air, and falls. There the Paris stabber stabs him in the stomach, killing him. Then the two drunk Vietnamese border guards kills them both and, for more chaos, Vitoon Sulngarm appears and explodes a hand grenade, killing everybody including him.
And for you? which drunk mass murderer would win a fight if they were to fight another drunk mass murderer?
