"On a tree by a river a little tomtit Sang "Willow, titwillow, titwillow" And I said to him, "Dicky-bird, why do you sit Singing ‘Willow, titwillow, titwillow?'. "Is it weakness of intellect, birdie?" I cried, "Or a rather tough worm in your little inside?" With a shake of his poor little head he replied, "Oh, Willow, titwillow, titwillow!""
