the blackbird does as blackbird should
he sings the morn in view
and at dusk, as sun dons hood,
farewell's the day's deep blue

and though the sloth seems lazy,
a-snoozing in the tree,
a sleep that might seem crazy
to you and to me

a sloth does as sloth is,
he cannot other be,
much as the black moth is
nocturnal frequentee

during the day, he lies under
leaf or vegetation,
it's all a part of the wonder
of G-d's machination

it's just man that has a say
in how he spends his hour,
he may choose to be gay,
blithesome as a flower

or saturnine and severe,
without a hint of cheer,
though DNA may play a part
man is ruler of his heart
