The ‘moth joke’ should be taught in university courses on humor, if there is such a thing. The joke teller (Norm) starts by telling the audience that the main character is a moth. Then he goes through ten minutes of rambling and humanizing the character in order to make the listener forget it’s a moth. By that time the listener thinks it’s just a person at a therapists office. Then *bang* comes the reminder it’s still a moth.. and the listener laughs at the silliness.
