Ponyville Ranger
Three things need to be made: 1: An image of Celestia and Luna either standing next to or inside of the Impala, or Impona as it might be called. 2: A fanfic with Celestia as Dean and Luna as Sam. And 3: Someone needs to takes clips from MLP and either make a PMV to Carry On My Wayward Son, or one of the really good animators needs to make an animation of it.
