Possessed of a twisted sense of humor, Harry was infamous for deploying unusual (and often dangerous) methods to try and reach his students, such as firing a gun off in the Dungeon in an effort to teach the unruly students there a lesson in respect (something Marla approved of), agreeing to become the faculty sponsor for a student branch of the National Rifle Association only to later deliver a disparaging speech against the organization (which he linked to an American glorification of gun violence), and starting up a "Suicide Club" to get kids to open up about their suicidal feelings.
