William Shakespeare said this quote

That such a slave as this should wear a sword,Who wears no honesty. Such smiling rogues as these,Like rats, oft bite the holy cords atwainWhich are too intrinse t' unloose; smooth every passionThat in the natures of their lords rebel,Being oil to the fire, snow to the colder moods,Renege, affirm, and turn their halcyon beaksWith every gale and vary of their mastersKnowing naught, like dogs, but following.
