From "The Ignominy of being Grown Up," by Dr.Samuel M.Crothers, in the Atlantic Monthly for July, 1906.
A very little boy made this story up "out of his head," and told it to his papa I think you littlest ones will like it; I do.
Once upon a time there was a little boy, and he wanted to be a cock-a- doo-dle-doo So he was a cock-a-doo-dle-doo.And he wanted to fly up into the sky.So he did fly up into the sky.And he wanted to get wings and a tail.So he did get some wings and a tail.
