The "unfortunate man" has all sorts of troubles. His sweetheart jilts him. He runs off with another man's wife, but is quickly captured. His friends cheat him. Now he can only hope a girl will "think more of my heart than she did of my face."
Not to be confused with the pop folk song "The Warranty Deed" (sometimes known as "The Unfortunate Man" or "The Very Unfortunate Man") about the poor lawyer and the disassembleable woman. - RBW, PJS
