Context: Rub-A-Dub-Dub was an English nursery rhyme TV series animated by Peter Lang and Alan Rogers of the Cut-Out Animation Co.  They were previously famous for Pigeon Street.  The series was produced by David Yates and Joe Wolf.  The title is a reference to the nursery rhyme Rub-a-dub-dub. Humpty Dumpty is a character in an English nursery rhyme, probably originally a riddle and one of the best known in the English-speaking world.  He is typically portrayed as a personified egg, though he is not explicitly described as such.  The first recorded versions of the rhyme date from late eighteenth-century England and the tune from 1870 in James William Elliott's "National Nursery Rhymes and Nursery Songs".  Its origins are obscure and several theories have been advanced to suggest original meanings. "London Bridge Is Falling Down" (also known as "My Fair Lady" or "London Bridge") is a traditional English nursery rhyme and singing game, which is found in different versions all over the world.  It deals with the depredations of London Bridge and attempts, realistic or fanciful, to repair it.  It may date back to bridge rhymes and games of the Late Middle Ages, but the earliest records of the rhyme in English are from the seventeenth century.  The lyrics were first printed in close to their modern form in the mid-eighteenth century and became popular, particularly in Britain and the United States in the nineteenth century. “Pop!  Goes the Weasel” is an English nursery rhyme and singing game.  It has a Roud Folk Song Index number of 5249.  The jack-in-the-box children’s toy often plays the melody. Frère Jacques ( , ] , in the nursery rhyme and in song more generally ] ; English: "Brother John"; Dutch: "Vader Jacob" (Netherlands) or "Broeder Jacob" (Flanders), German: "Bruder Jakob", Italian: "Fra' Martino", Polish: "Panie Janie", Danish: "Mester Jakob"), is a nursery rhyme of French origin.  The rhyme is traditionally sung in a round. Tweedledum and Tweedledee are fictional characters in an English nursery rhyme and in Lewis Carroll's "Through the Looking-Glass, and What Alice Found There".  Their names may have originally come from an epigram written by poet John Byrom .  The nursery rhyme has a Roud Folk Song Index number of 19800.  The names have since become synonymous in western popular culture slang for any two people who look and act in identical ways, generally in a derogatory context. "A Wise Old Owl" is an English language nursery rhyme.  It has a Roud Folk Song Index number of 7734 and in The Oxford Dictionary of Nursery Rhymes, 2nd Ed.  of 1997, as number 394.  The rhyme is an improvement of a traditional nursery rhyme "There was an owl lived in an oak, wisky, wasky, weedle." Plop Goes the Weasel is a 1952 Foghorn Leghorn cartoon, directed by Robert McKimson and released by Warner Bros. in 1953.  The title is a pun on the song title "Pop Goes the Weasel".  The aforementioned tune is played during the intro and it is played almost every time the weasel appears and subsequent cartoons involving the weasel vs Foghorn. Mots D'Heures: Gousses, Rames: The D'Antin Manuscript ("Mother Goose's Rhymes"), published in 1967 by Luis d'Antin van Rooten is purportedly a collection of poems written in archaic French with learned glosses.  In fact, they are English-language nursery rhymes written homophonically as a nonsensical French text (with pseudo-scholarly explanatory footnotes); that is, as an English-to-French homophonic translation.  The result is not merely the English nursery rhyme but that nursery rhyme as it would sound if spoken in English by someone with a strong French accent.  Even the manuscript's title, when spoken aloud, sounds like "Mother Goose's Rhymes" with a strong French accent. Visits to St Elizabeths is a poem by Elizabeth Bishop modelled on the English nursery rhyme "This is the house that Jack built".  The poem refers to the confinement between 1945 and 1958 of Ezra Pound in St Elizabeths Hospital, Washington, D.C.  The nursery rhyme style gives an unusual effect to the strange or unsettling descriptions of a psychiatric hospital in the poem.  Likewise the poem treats Pound ambivalently describing him by turns as "honored", "brave", "cruel", and "wretched" among other things.
