My wife is gorgeous and one of a kind, and I couldn''t possibly be more proud of my beautiful wife. Of course that didn''t stop me from taking compromising pictures while she wasn''t looking. If some of the photos of my hot wife Rhonda in this bikini are blurry, it''s because my hands were shaking! This is a room full of my wife and I''s very very good friends. -- Russell Crowe as Nicholas Hostetler, Mayor of New York City in Broken City (2013) The joint possessive my wife and I''s sounds incorrect to me, but it also sounds rather tempting and difficult to fix! Because the phrase follows of, it would seem that I (subjective case) should be changed to me (objective case).
