What are you and your kids' favorite books to read together?

My son was just born in November, and although he obviously won't know any better, I thought this year for Christmas I would just buy him a bunch of books to add to his small collection. What are some great children's books? He already has Where the Wild Things Are, I bought it because it's one of MY favorite books. He also has some Winnie the Pooh treasuries, and a couple of random Little Golden Books given to me as shower presents..
