Asparagus

"They left, saying they would return after five o'clock if they received permission to prune, and on their way out they muddied the interior terrace and the drawing room and ripped Fermina Daza's favorite Turkish rug. Needless disasters, all of them, because the general impression was that the parrot had taken advantage of the chaos to escape through neighboring patios. And in fact Dr. Urbino looked for him in the foliage, but there was no response in any language, not even to whistles and songs, so he gave him up for lost and went to sleep when it was almost three o'clock. But first he enjoyed the immediate pleasure of smelling a secret garden in his urine that had been purified by lukewarm asparagus."
