So the three-legged man took control of his feet and bought a friend for Charlie, Chaplin the cat, in hopes that Charlie's peeing problem is the symptom of a need for affection, which the three-legged man could not provide due to depression surrounding recent financial and marital troubles.
This depressed the man so much that he kicked Chaplin with the third leg his wife so despised. This enraged Charlie, who was getting affection from Chaplin (which could not be provided by the man due to depression surrounding recent financial and marital troubles), and Charlie peed on the three legs as revenge. And so, the three-legged-man was back to square one.
One day, Jim-Bob, who was alternatively known as Captain Lucretius of Anthenor, invited a visitor into their cardboard box. This man introduced himself to Charlie as The Great Captain of the West, and he had an important tale to tell.
The Great Captain of the West was so important, and his tale of such magnitude, that the man had coffee! He shared a sip of the glorious drink with Jim-Bob and the three-legged-man (who didn't remember his own name out of grief at this point), and then began to talk.
The Great Captain told the man that his great-grandfather had been King of Anthenor, that his real name was Erasmus Xerxes Thessalius Rhadamanthys Alexandros Lucius Eurystheus Gaius the Third (or EXTRA LEG for short), and that he was heir to the throne of Anthenor.
The Captain told tales of how EXTRA had performed a miraculous evacuation when his cardboard castle in Los Angeles was attacked, saving all four of the squatters there from the terrible fate they would surely have suffered at the hands of the evil king, Linus Englebert Geoffrey Charles Hubert Owen Prometheus Prascant Evan Robert (or LEG CHOPPER). Together, the Captain said, EXTRA and the Captain could retake the castle.
Back in the Province of Legaloria, Lucretius, Steve and the Great Captain were trying to raise an army. Unfortunately, they had not had much luck, as they had only managed to recruit a single woman, named Sarah Ann Virgil Iris O'Reilly. However, Sarah was widely regarded as the greatest warrior in all of Legaloria, having gained the title by defeating an entire battalion of the New Anthenorian Army single-handedly.
