Nabokov wrote on index cards
at a lectern, in his socks,
St John of the Cross did his best stuff
imprisoned in a box.
and my favourite:
Karl Marx squeezed his carbuncles
while writing Das Kapital
and Paul Gauguin he b******d off man
and went all tropical
not to mention:
So if you've got a trumpet, brother,
get on your feet and blow it.
If you've got a field, that don't yield,
get out there and hoe it.
