Can't delete Untitled Event in iPhoto '09

In my iPhoto Library under Photos I have 2 Untitled Events. I renamed them Untitled 1 and Untitled 2. Neither contains any photos and when you go to Events neither of them is showing there. The problem is it won't allow me to deleted these 2 Untitled events. Right-clicking and the "Move to Trash" option is grayed out and CMD+Delete doesn't work either. Help?
