Long, long ago up on top of a sign
Lived an old rotten sponge and a small piece of twine.
Said the sponge to the twine, “I am feeling quite fine.”
“But youre rotten, my friend.” said the small piece of twine.

“That I am, that I am,” said the sponge to the twine.
“But I think you'll find me in the prime of my time.
For I know when it's wrong and when it is fine
To use an apostrophe. You fail, Mr. Twine.”
