When icicles hang by the wall,
And Dick the shepherd blows his nail,
And Tom bears logs into the hall,
And milk comes frozen home in pail,
When blood is nipp'd and ways be foul,
Then nightly sings the staring owl,
Tu-who;
Tu-whit, tu-who — a merry note,
While greasy Joan doth keel the pot.

Love's Labour's Lost [1594—1595], V, ii, 920
