When he is taken to court the next morning, The Boss relates a tale about being a slave belonging to Earl Grip, who had been sent into London to fetch a physician when the Earl became suddenly ill; he had been running as fast as he could when he happened to run into this man, who seized him by the throat and began beating him. The Boss is quickly released, and he returns to the slave quarters and finds them all gone. He learns that the slaves had revolted in the night and had killed the slave master. All the slaves have been condemned to die in the next day or so.
The Boss quickly buys some new clothing and arranges a disguise of sorts. Then he finds the telephone office, where he forces the attendant to put in a call to Camelot and to ask for Clarence. After a time, Clarence is reached. They decide that a mighty force of knights will be the best way to handle the situation; Clarence assures him that they will leave in half an hour.
After he leaves the telephone office, The Boss decides to try and make contact with people he knows. However, he is over-confident and walks, literally, into the shackles of the law and is put into prison with the other slaves. There, he learns that they are to be hanged in the middle of that afternoon, before the knights can get from Camelot to London.
About four in the afternoon, the slaves are taken out to be hanged; it is a superb day. The king creates a diversion when he leaps up and proclaims himself to be Arthur, King of Britain. Of course, the crowd does not believe a word he says; instead, they are amused, and they call for him to speak, but he will not.
Three slaves are hanged in short order, and the blindfold is then put on the king. Suddenly, five hundred knights in mail come riding up on bicycles, led by Sir Launcelot. The knights swarm upon the scaffold, tossing the sheriffs and others off, and freeing the king and The Boss. Clarence has also come along, and he explains how he has had the knights drilling for a long time; they have just been waiting for a chance to show off their newly acquired skills.
