All's fair in love and war again

 

 Against such lewdsters, and their lechery,

Those that betray them do no treachery.     

 

-- William Shakespeare, The Merry Wives of Windsor, Act 5, Scene 3

The righteous sleep undisturbed . . . by elves

Where's Pede?--go you, and where you find a maid,

That, ere she sleep, hath thrice her prayers said,

Rein up the organs of her fantasy;

Sleep she as sound as careless infancy;

But those that sleep, and think not on their sins,

Pinch them, arms, legs, backs, shoulders, sides, and shins.

-- William Shakespeare, Merry Wives of Windsor, Act V Scene V
