Huck enjoys the circus because it is pleasant relief from the king and the duke and the problems helping Jim escape. He loves seeing the costumes, acrobats and clowns. Ironically, Huck, who is somewhat of a con artist himself, doesn't recognize a con when a supposed drunk insists on riding the horses. The drunk turns out to be a wonderful rider, indicating that the entire event was a set-up. But Huck never catches on and throughly enjoys the act.
