IF ALL THE SEAS

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!
