Once in Miami, Joe woos Sugar by assuming a second disguise as a millionaire named Junior, the heir to Shell Oil, while feigning disinterest in Sugar. An actual millionaire, the much - married aging mama 's boy Osgood Fielding III, (Joe E. Brown) tries repeatedly to pick up Daphne, who rebuffs him. Osgood invites Daphne for a champagne supper on his yacht. Joe convinces Daphne to keep Osgood occupied onshore so that Junior can take Sugar to Osgood 's yacht, passing it off as his. Once on the yacht, Junior explains to Sugar that, due to psychological trauma, he is impotent and frigid, but that he would marry anyone who could change that. Sugar tries to arouse some sexual response in Junior, and begins to succeed. Meanwhile, Daphne and Osgood dance the tango ("La Cumparsita '') till dawn. When Joe and Jerry get back to the hotel, Jerry explains that Osgood has proposed marriage to Daphne and that he, as Daphne, has accepted, anticipating an instant divorce and huge cash settlement when his ruse is revealed. Joe convinces Jerry that he can not actually marry Osgood.
