Sir Joseph comes on board with his sisters, cousins, and aunts.  He says he rose from humble beginnings to be "the ruler of the Queen's Navee", although he has no qualifications.  He then delivers a lesson in etiquette, telling the Captain that he must always say "if you please" after giving an order for "A British sailor is any man's equal".  He has composed a song to illustrate that point.
