I found references to the Benign Violation Theory of humor. Click on the link to read or download the PDF.
A. Peter McGraw & Caleb Warren wrote:
Theories of humor often suggest that humor requires a perceived violation, or something that disrupts people’s sense of how the world ought to be (Freud, 1928; Gruner, 1997; Veatch, 1998). Moral psychology theories, however, typically suggest that the very same types of normative breaches elicit negative emotions, such as disgust, rather than amusement (Rozin, Lowery, Imada, & Haidt, 1999). We hypothesize that humor is elicited by benign violations and show that moral violations that simultaneously seem benign elicit laughter and amusement in addition to disgust.
Good article, if a bit lofty.
