Grook

A grook ("gruk" in Danish) is a form of short aphoristic poem. It was invented by the Danish poet and scientist Piet Hein. The name is short for "GRin & sUK" which means "cry and moan" in Danish. The poems were meant as a spirit-building, yet slightly coded form of passive resistance against Nazi occupation during World War II. The characteristic irony, paradox, and the duality of quantum logic of the poems is the only distinguishing form.

EDIAMATIC
Know it all cold?
Or lank with acedia?
Share and be bold;
Come build Wikipedia.

ASSY-METRY
There's nothing that goads
Like no-passing roads
With a slowpoke in front
And a hot rod in back ---
'Cause you'd never speed
It's just that you need
To get past that grunt 
And away from that devil on crack.

DRIVE ON
Schadenfreude Grook
Flare spoor, white powdery burns:
Like funerals without the urns.
Mark the passages of lives before eyes
And the uttering of inhuman cries.
Still we're always glad to see'um,
Cause it means we didn't be'em.
--Anon.

THE ROAD TO WISDOM?
Well, it's plain
and simple to express.
Err and err and err again,
but less and less and less.
-- Piet Hein.
