Johnny usually stuck to business, but would sometimes engage in romantic dalliances with women he encountered in his travels; later episodes gave Johnny a steady girlfriend, Betty Lewis. Johnny's precious recreational time was usually spent fishing, and it was not uncommon for Johnny's clients to exploit this favorite pastime in convincing him to take on a job near good fishing locations.
