But he did invent the sandwich!

It is hard to say whether Lord Sandwich, in charge of the navy, or Lore George Germain, in charge of military affairs, did more damage to the British cause. Sandwich, a cynical debauchee, termed one of the most dissolute men of Georgian England, won immortality of a sort of having meat placed between slices of bread so that he could lunch without having the leave the table and break his luck while gambling. By neglecting the material condition of the ships and by alienating the Whig admirals, Sandwich probably did more damage to the navy entrusted to his care than any hostile French admiral had ever done.
