"Caesar's lean and hungry friends"
A reference to Shakespeare’s Julius Caesar, Act I, scene ii, in which Caesar spies Cassius (the primary instigator of his future assassination) talking with Brutus and says “Yond Cassius has a lean and hungry look,/He thinks too much; such men are dangerous.” Caesar contrasts Cassius with fat, contented men, with whom he would prefer to surround himself (and wisely, too). The historic Cassius was known as Gaius Cassius Longinus (c. 85 BCE – 42 BCE), a Roman senator, practitioner of Epicurean philosophy, and for two years the governor of the province of Syria.
