Two brothers nearly come to blows over a broken rattle until a monstrous crow startles them out of it, followed by an unrelated snippet about two old women stuck up an apple tree. It's a rhyme in two odd halves, better known today for lending its names to Lewis Carroll's pair in Through the Looking-Glass.
From Mother Goose / Nursery Rhymes (traditional). See the whole collection.
Tweedle-dum and Tweedle-dee
Resolved to have a battle,
For Tweedle-dum said Tweedle-dee
Had spoiled his nice new rattle.
Just then flew by a monstrous crow,
As big as a tar barrel,
Which frightened both the heroes so,
They quite forgot their quarrel.
OH, DEAR!
Dear, dear! what can the matter be?
Two old women got up in an apple-tree;
One came down, and the other stayed till Saturday.
