The iron tongue of midnight hath told twelve;
Lovers, to bed; 'tis almost fairy time. [ William Shakespeare ]

I have heard they are the most lewd impostors,
Made of all terms and shreds, no less beliers
Of great men's favours than their own vile medicines,
Which they will utter upon monstrous oaths;
Selling that drug for two pence ere they part.
Which they have valued at twelve crowns before. [ Ben Jonson ]
