When Caesar says: “Let me have men about me who are fat,” he is thinking about Brutus.

When Caesar says, "Let me have men about me who are fat," he is not directly thinking about Brutus. This quote is from Act 1, Scene 2 of Shakespeare's "Julius Caesar." Caesar is expressing his mistrust of lean and hungry-looking men, implying that they are ambitious and dangerous. He prefers to be surrounded by content and satisfied men, who he perceives as less likely to betray him.

However, Brutus, who is Caesar's friend and later one of his assassins, is not fat. Caesar's statement could be seen as ironic, as it is Brutus - not a lean and hungry man - who ends up betraying him. So, while Caesar is not directly thinking about Brutus in this quote, it indirectly relates to Brutus and his ultimate betrayal.
