The superb winning entry of a competition run by New Statesman magazine (2009-12-14) to summarize a work of literature with a limerick, due to performance poet and photographer Anneliese Emmans Dean:

From the farm they banished the people.
“Hurrah!” cried the beasts. “We’re all equal!”
But superior plotters,
With trotters, the rotters,
Took over. The End. (There’s no sequel.)
