The occasional role of humor as a vehicle for moral criticism is investigated. I begin by distinguishing between this particular role and the other kinds of ways in which humor and amusement might be regarded through a moral lens, consider historical approaches to humor that corroborate the kind of role for it on which my investigation focuses, and end by considering contemporary examples of irony, sarcasm, and satire as vehicles of just the kind criticism under review (for instance, the July 21, 2008, cover of the New Yorker).
