"The world is grown so bad, that wrens make prey where eagles dare not perch."(Quoted in Act I, Scene III). This is a quote from William Shakespeare's play Richard III. At its heart, it means that the world is turned upside down. The wren is usually considered a timid bird, and eagles are seen as birds of prey. Shakespeare has turned that around and amplified it. Not only for him is the wren a bird of prey, but it even goes in search of prey where eagles are too timid to even perch.

In Shakespeare's play "Measure For Measure", he says that 'liberty plucks justice by the nose'. This is a similar meaning to the above quote.

In modern English, when individuals want to say that things are the wrong way round, or that the world has gone mad, they often say: "The lunatics are running the asylum." This is an often used idea that most people (artists, writers, critics, etc.) know very well. They state it over and over; they tell us "the world is topsy turvy and nothing is the way that it was; everything is upside down".
