The peddler doesn't come across as a humorous person, although one can locate a subtle sense of humor in the way he thinks about the world as being a giant rattrap. He is singularly pleased by this thought of his because it provides him with the opportunity of thinking 'ill' of the world that is not kind to him. It is clearly visible that whenever he gets caught unaware, in the web of deceit spun by his scheming mind, he hides behind the thought that the world is a rattrap and he merely a prey. Thus, he lightens the mood and theme of the story and makes us endear him.
