Books are kept or returned and for some that's okay But to an LFL, this one would come back one day. It's been proven that those who stow this kind of books Make embarrassing burps that evoke dirty looks. Some are subject to irksome calamities too And suffer from spillage of ink and of glue And of syndromes and ailments contract a range: Impetigo, athletes foot, pink eye and mange Blackened big toenails and incisor stains Hangnails and baldness and varicose veins So it's best to put back on an LFL shelf Books like this one which can fend for itself.
