1. Rules Of Space Opera

    9. There should be a captain. If there is not a captain, there should be a special agent. If there is not a special agent, there should be a cadet with a future. If there is no cadet with a future, there should be a mercenary with a dark past.

    If there is no mercenary with a dark past, there should be a wisecracking stowaway. If there is no wisecracking stowaway, there should be a witch. If there is no witch, there should be a scientist. If there is no scientist, just remake Spaceballs.
