Henry Wadsworth Longfellow
Beware!
I know a maiden fair to see,
  Take care!
She can both false and friendly be,
  Beware! Beware!
  Trust her not,
She is fooling thee!
She has two eyes, so soft and brown,
  Take care!
She gives a side-glance and looks down,
  Beware! Beware!
  Trust her not,
She is fooling thee!
And she has hair of a golden hue,
  Take care!
And what she says, it is not true,
  Beware! Beware!
  Trust her not,
She is fooling thee!
She has a bosom as white as snow,
  Take care!
She knows how much it is best to show,
  Beware! Beware!
  Trust her not,
She is fooling thee!
She gives thee a garland woven fair,
  Take care!
It is a fool's-cap for thee to wear,
  Beware! Beware!
  Trust her not,
She is fooling thee!
