In an exchange with John Montagu, 4th Earl of Sandwich, where the latter exclaimed, "Sir, I do not know whether you will die on the gallows or of the pox," Wilkes is reported to have replied, "That depends, my lord, on whether I embrace your lordship's principles or your mistress." Fred R. Shapiro, in "The Yale Book of Quotations" (2006), disputes the attribution based on a claim that it first appeared in a book published in 1935, but it is ascribed to Wilkes in Henry Brougham's "Historical Sketches" (1844), related from Bernard Howard, 12th Duke of Norfolk, who claims to have been present, as well as in Charles Marsh's "Clubs of London" (1828). Brougham notes the exchange had in France previously been ascribed to Honoré Gabriel Riqueti, comte de Mirabeau and Cardinal Jean-Sifrein Maury.
