Duffy was a firefighter and a friend of John Hallam's who went on a Brigade training course with him. Duffy went to the course intent on boozing and womanizing. Hallam refused to join in, preferring to concentrate on studying, so Duffy smeared lipstick on his underwear. When Sandra found it she made John sleep on the sofa. When the watch found out they had fun singing "There's lipstick all over my y-fronts" and "Have you seen the y-front man" at him.
