Children's Books

So for my writing kiddie lit. class, we have to bring in a kid's book we like and one we don't like. I put a poll up on the side of my blog for the choices I'm debating between for the book that I like. Now, as a little girl, I can't remember really disliking any books, so do any of you remember a book from your childhood that you really detested? Please, please vote in the poll so you can help me in my indecisiveness! :) And if you can recommend any books (picture books, really) that are quite awful, let me know! Thanks!
