A tiny riddle rhyme about going to fetch something, losing it, and bringing home the loss instead. Its puzzle logic makes it a good one for a slightly older child to turn over.
From Mother Goose / Nursery Rhymes (traditional). See the whole collection.
I went to the wood and got it;
I sat me down to look for it
And brought it home because I couldn't find it.
