A cumulative what-if rhyme that stacks one impossible idea on another until it ends in an enormous splash. The building repetition makes it a joy to speed up as you go.
From Mother Goose / Nursery Rhymes (traditional). See the whole collection.
If all the seas were one sea,
What a _great_ sea that would be!
And if all the trees were one tree,
What a _great_ tree that would be!
And if all the axes were one axe,
What a _great_ axe that would be!
And if all the men were one man,
What a _great_ man he would be!
And if the _great_ man took the _great_ axe,
And cut down the _great_ tree,
And let it fall into the _great_ sea,
What a splish splash _that_ would be!
