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]
Hot Diggity (Dog Ziggity Boom) The phrase "hot diggity dog!" dates to at least 1928, when Al Jolson was recorded saying "Hot diggity dog! Hot kitty! Hot pussycat! Didn't I tell you you'd love it?" after a performance of the tune "There's a Rainbow 'Round My Shoulder".
