How is Bob Ewell characterized in Chapter 17? Use 2 details to support?

the Ewells belong to the bottom set of Maycomb's whites. Mr. Ewell shows himself to be arrogant and crude. Maycomb reluctantly has bent the laws for the Ewells, and Mr. Ewell's manner is of one who is beyond the law. He is described as a "bantam cock" who struts around arrogantly yet ridiculously, and he tries to invoke the good humor of the audience, whines to the judge about being asked to prove his ability to write, and offends everyone with his language, putting the court into five minutes of uproar. The chapter depicts him as brutish, insensitive, and confident of his ability to get away with his perjury.
