"SEE-SAW, MARGERY DAW, / THE OLD HEN FLEW OVER MALT HOUSE" by ANONYMOUS
Last Line: "AND THIS IS IT, THIS IS IT, THIS IS IT"
SEE-SAW, Margery Daw, The old hen flew over the malt house; She counted her chickens one by one, Still she missed the little white one, And this is it, this is it, this is it.
