Theme episodes are my favorite, and one of the best things about Supernatural is that with so many creatures cycling in and out, practically every week feels like a theme episode. Come Jan. 26, the Winchester boys are headed to the medieval fair to help solve some murders. That's exciting and all, but the best part is that Dean (Jensen Ackles) dresses up like a medieval peasant. It's live-action role-playing at its finest. Check out all the pictures from the episode and let us know if you'll be tuning in.
