What is something you own a ridiculous amount of?

My answer to this question would be books and DVDs. I love reading books and watching shows and movies to the point that I've found myself with a truly ridiculous amount of both. I no longer have room on any of my bookcases and have just started storing them in boxes. But they are taking up too much space and I need to find some creative ways to store them because at the moment I don't want to get rid of anything. I enjoy my not so little collection that apparently keeps growing.
