What's Your Favourite Episode From Season One?

Well, we've seen all the Episodes we possibly can. If you're like me and reminisce about each Season, this is the good part. What's your favourite Episode from the first Season and why? I'll go first.

My favourite Episode has to be Scarecrow. It's creepy, funny at times and it gives us viewers the chance to see Dean and Sam away from each other for a wee while. I especially liked the bit when Dean's tied to the tree and claims to be "working on it" for a plan. Sure, Sam turns up in the end and saves the day but it IS Dean's Episode I think.
