Piet Hein (16th December 1905 – 17th April 1996), Danish poet, mathematician, inventor and scientist is perhaps best known for his short poems, grooks. They are typically ironic and satirical. They are typically illustrated.
Her is an example.
On Problems
Our choicest plans
have fallen through,
our airiest castles
tumbled over,
because of lines
we neatly drew
and later neatly
stumbled over.
