The dog with the machine gun: chapter 1:

Once upon a time, there was a dog with a machine gun, who was so bored, so he decided to take a walk in the rotting slums. Suddenly, a wolf got in his way and shouted: "I challenge you to a battle!" The dog of course accepted and immediately won and took all his money. Meanwhile, a fire salamander in the sewers was doing the same thing, only with poor starving animals with no way of defending themselves.

They lived happily ever after. The end.
