My favorite poem, from memory is:

Grandpa Dropped His Glasses
(Leroy F. Jackson)

Grandpa dropped his glasses once
In a pot of dye,
And when he put them on again
He saw a purple sky.
Purple fires were rising up
From a purple hill,
Men were grinding purple cider
at a purple mill.
Purple Adeline was playing
With a purple doll;
Little purple dragon flies
Were crawling up the wall.
And at the supper-table
He got crazy as a loon
From eating purple apple dumplings
With a purple spoon.
