Le Coeur a gaz, (1923, Tristan Tzara)

it was three short acts
& the last spectacle on the program
was a complete dada farce,
with a trumpet in front of the infuriated audience
playing the Marseillaise!
this time around, there were no professional
actors to storm out singing
about the utter pointlessness
of playing body parts while wearing cubist costumes
made of stiff tubing
which reduced their walking to a geriatric shuffle.
out front, the police heard the angry voices and stormed inside
where fist fights between the dadaists and the future
surrealists began in earnest, with several badly beaten
and in no mood to be mollified.
shouts for order bounced off walls, hitting no one,
but damage to the theater was considerable.
seats were smashed and faces bloodied.
Aragon tried to rescue Eluard while
the police arrested the entire audience,
but later concluded it was all a big misunderstanding.
