to tweet, to who, a merry note

An article about twitter brought 'tu-whit, tu-who' to my mind - this classic little Shakespeare poem...when icicles hang by the wall...

Winter
    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 nipped 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.
    When all aloud the wind doth blow,
        And coughing drowns the parson's saw,
    And birds sit brooding in the snow,
        And Marian's nose looks red and raw
    When roasted crabs hiss in the bowl,
    Then nightly sings the staring owl,
        Tu-who;
    Tu-whit, tu-who: a merry note,
    While greasy Joan doth keel the pot.
        William Shakespeare
