Explain how Ratched shows the other patients that McMurphy is 'crazy like a fox'.

She pastes up statements of the patients’ financial doings over the past several months, suggesting that McMurphy has made money from the rest of the patients. Nurse Ratched sets up a meeting without McMurphy, at which she implies that he is trying to fleece them of their money and that this is his only motivation in befriending them. She tells them that McMurphy is no martyr or saint but an old-fashioned con artist.
