A setting of the eponymous E. E. Cummings poem.
No. 63 in the 100 Poems project.
The entire poem is a couplet which reads:
a politician is an arse upon
which everyone has sat except a man
The score reads:
Mass action involving a large group of people performing the following:
1) Handfuls of water spontaneously dropped on the floor [splat!]
2) Small cups of water dumped suddenly from a large height into large buckets of water
3) Glasses thrusted upside-down into medium-sized buckets of water and allowed to overturn, releasing their air [glug!]
After some time has passed, the speaker reads the couplet loudly over the ruckus behind him.
Actions continue for some time after that.
