Mark but this flea, and mark in this, How little that which thou deniest me is; It sucked me first, and now sucks thee, And in this flea our two bloods mingled be; Thou know’st that this cannot be said A sin, nor shame, nor loss of maidenhead,     Yet this enjoys before it woo,     And pampered swells with one blood made of two,     And this, alas, is more than we would do. – Oh stay, three lives in one flea spare, Where we almost, nay more than married are. This flea is you and I, and this Our marriage bed, and marriage temple is; Though parents grudge, and you, w’are met, And cloistered in these living walls of jet.     Though use make you apt to kill me,     Let not to that, self-murder added be,     And sacrilege, three sins in killing three

Cruel and sudden, hast thou since Purpled thy nail, in blood of innocence? Wherein could this flea guilty be, Except in that drop which it sucked from thee? Yet thou triumph’st, and say’st that thou Find’st not thy self, nor me the weaker now;     ’Tis true; then learn how false, fears be:     Just so much honor, when thou yield’st to me,     Will waste, as this flea’s death took life from thee.

As far as we know, the earliest example of the nursery rhyme is in Nancy Cock’s Pretty Song Book for All Little Misses and Masters, circa 1780.  Here are the opening lines: “Taffy was a Welshman, Taffy was a thief, / Taffy came to my house and stole a piece of beef.” The name “Taffy” may come from “Dafydd,” a Welsh name related to “David,” and the Taff, the river in Cardiff.
