What Is funny or ironic about scout wearing a ham?

In Harper Lee's novel "To Kill a Mockingbird," Scout participates in a school play where she wears a ham costume. The humor and irony in this situation stem from the fact that Scout, a young girl who is typically independent and outspoken, is forced to wear a ridiculous and degrading costume. Additionally, the choice of a ham costume is symbolic of the town's prejudice and narrow-mindedness, as it is meant to represent the town's view of the Finch family as outsiders or "different."
