“CAESAR: Let me have men about me that are fat,
Sleek-headed men, and such as sleep a-nights.
Yond Cassius has a lean and hungry look.
He thinks too much. Such men are dangerous.

ANTONY:Fear him not, Caesar; he’s not dangerous.
He is a noble Roman, and well given.

CAESAR: Would he were fatter! But I fear him not.
Yet if my name were liable to fear,
I do not know the man I should avoid
So soon as that spare Cassius. He reads much,
He is a great observer, and he looks
Quite through the deeds of men.”

― Julius Caesar
