This episode was produced before "My Dumb Luck", so Dr. Kelso is still Chief of Medicine.
Due to the 2007-2008 writer's strike creator Bill Lawrence never got to complete the season, so the episodes were rearranged with this episode being the "finale" for NBC.
In a nod to "The Princess Bride", Dr. Cox as the knight introduces himself to the monster by saying, "my name is Percival Cox. You're killing my friend. Prepare to die".
Bill Lawrence's wife Christa Miller wanted an episode for her kids to be able to watch, so Bill ordered a fairy tale episode to be made.
Last episode aired on NBC before moving to ABC.
