"If you give a mouse a cookie" should be on everyone's list! This was the book my Mom read to me at night when I was a kid. Well, when she would put me to bed, which wasn't too often, but I cherished those moments with her. I loved listening to her act out the little mouse as he kept asking for things. The lesson here is to be happy w/what you have instead of continually wanting more-- that's how I took it, at least.
