Robin Goodfellow

"that shrewd and knavish sprite

Call'd Robin Goodfellow: are not you he

That frights the maidens of the villagery;

Skim milk, and sometimes labour in the quern

And bootless make the breathless housewife churn;

And sometime make the drink to bear no barm;

Mislead night-wanderers, laughing at their harm?

Those that Hobgoblin call you and sweet Puck,

You do their work, and they shall have good luck:

Are not you he?
