Only You Can Save Mankind/Fridge

"The Captain: Remember, only you can save mankind.
 * Only You Can Save Mankind
 * Johnny Maxwell has to save a fleet of alien ships from other players, the alien Captain mentions that the name for her planet is "Earth". Only on my fourth reading did I realize that the title of the book didn't refer to humans at all... - Cidolfas
 * The Captain says that the name the ScreeWee have for their planet is "Earth". Considering that, the title quite likely doesn't refer to humans at all. No need to guess.

Johnny: And I said I already--

The Captain: ScreeWee is only the human name for us. Have you ever wondered what the ScreeWee word for ScreeWee is?"
