O, while you live, tell truth, and shame the Devil!
Those that are good manners at the court are as ridiculous in the country, as the behavior of the country is most mockable at the court.
By-and-by is easily said.
O teach me how I should forget to think (1.1.224)
This cold night will turn us all to fools and madmen.
No man means evil but the devil, and we shall know him by his horns.
