Smallville fans, I need your help! #Smallville

Now that Smallville has aired its finale, and everything has set in, I'm planning on doing a Top Ten Cases that will rank the most stand out episodes (I'm always reluctant to refer to anything as the "best"). With nearly 220 episodes under its belt, it's awfully difficult to narrow the list down to ten. So, loyal fans, I'm hoping that some of you might offer me a suggestion. Please e-mail me any episodes that come to mind, and I'll see if they warrant a place on my personal list.

Thanks in advance for your help!
