Huckleberry Finn- Chapter 22

They (a mob) went to hang Sherburn who explained to them from his roof that they were cowards and they realized everything he was saying was true and they left. Sherburn was actually smart about his confrontation with the mob. Then Huck went to the circus where a drunk man wanted to ride a horse and the ringmaster let him. He ended up fooling everyone because he wasn't really drunk, he was just another part of the show. They had their play, but it wasn't successful so the duke made another handbill about another play that only admitted males. He thought that would get people wondering and want to go then. When I am reading this chapter, don't people wonder who they are? Town people usually know everyone else in the town, and if no one ever saw them before, wouldn't they question why they are there?
