where does the expression going to see a man about a dog come from
See a man about a dog The earliest confirmed publication is the 1866 Dion Boucicault play Flying Scud[2] in which a character knowingly breezes past a difficult situation saying, "Excuse me Mr. Quail, I can't stop; I've got to see a man about a dog."[3][4] In a listing for a 1939 revival on the NBC Radio program America's Lost Plays, Time magazine observed that the phrase was the play's "claim to fame".[5]
Who's That Man The narrator discusses returning to the home in which he used to reside. His ex-wife, children and their family dog still live in the residence, but the wife's new husband has now taken the place of the narrator.
