Cinderella dressed in yella Book

Mary had a little lamb.
She gave it castor oil.
And everywhere that Mary went,
It fertilized the soil.

I worked in a bookstore for about a year after university, while deciding where and how to embark on my career, and this book (and several like it) was one of the hidden treasures of the children's department, in a tiny section called "Children's Anthropology."

I finally got around to reading it cover to cover, and it was a lot of fun.
