I have just discovered that several versions of this probably apocryphal story have been circulating for years. Why had I never heard it until now?
On a visit to the Elysée Palace, Dorothy Macmillan said to Mme de Gaulle: "Now that your husband has achieved so much, is there any particular wish you have for him?", to which Madame replied: "Yes, a penis."
There was a stunned silence until General De Gaulle looked up and said: "Ah yes, 'appiness is what we all want."
