''Mary, Mary'' is a ComedyOfRemarriage by Jean Kerr.

The play is about the professional and romantic headaches of Bob [=McKellaway=], a bright, sensible fellow who heads a small publishing company, and the four guests he invites to his home-office apartment:
* Tiffany Richards, a wealthy, no-nonsense young woman who is Bob's fiancée;
* Oscar Nelson, a tax lawyer who explains to Bob that, what with the alimony the court ordered him to pay, he's not making ends meet and certainly can't afford a second divorce;
* Dirk Winsten, a Hollywood actor who was once in the Navy with Bob, with literary aspirations and some surprising insights, and
* Mary [=McKellaway=], Bob's ex-wife, a highly moody woman who tends to crack jokes at the wrong moments.

Creator/WarnerBros' 1963 film version starred Creator/DebbieReynolds as Mary, and featured Barry Nelson (Bob) and Michael Rennie (Dick) reprising the roles they played on stage.

Not to be confused with the gospel music duo Mary Mary, or the song "Mary Mary", recorded by Music/TheMonkees among others.
