Beware, my friend! of crystal brook, <br />Or fountain, lest that hideous hook, <br />Thy nose, thou chance to see; <br />Narcissus' fate would then be thine, <br />And self-detested thou wouldst pine, <br />As self-enamour'd he.<br /><br />William Cowper<br /><br />http://www.poemhunter.com/poem/on-an-ugly-fellow-from-the-greek/
