John Wilkes

'He was well known for his verbal wit and his snappy responses to insults. For instance, when told by a constituent that he would rather vote for the devil, Wilkes responded: "Naturally". He then added: "And if your friend decides against standing, can I count on your vote?" On another occasion, in an exchange with John Montagu, the Earl of Sandwich, who declared "Sir, I do not know whether you will die on the gallows or of the pox." Wilkes replied "That, sir, depends on whether I embrace your principles or your mistress."'
