Bernard Shaw - I Am Going Home.

Cows happily chew the cud.
Pigs wallow in the mud.
Cats purr when they are stroked,
Salmon is expensive when it is smoked.
Giraffes never get sore throats.
Elephants do not need overcoats.
Wolves howl at the moon.
Turtledoves never swoon.
Ducks swim in rivers and lakes.
Snakes in the desert rattle and shake.
Monkeys swing around in the trees.
From flowers pollen is gathered by the bees.
Now if you will kindly finish this poem on your own,
I have had enough and I am going home.

Bernard Shaw
