A man that keeps more than one mistress. A country gentleman, who kept a female friend, being reproved by the parson of the parish, and styled a whore-monger, asked the parson whether he had a cheese in his house; and being answered in the affirmative, ‘Pray,’ says he, ‘does that one cheese make you a cheese-monger?’
