Don't Forget Your Spacesuit, Dear

From the back cover of the Baen first edition: The apron string theory of spacetime! So, you think things will be any different in the future, in space, in other dimensions where magic works? Wash your mouth our with soap! Mother will always know best. The galactic emperor, master of a million suns, just better not get too busy to call his mother. Starship troopers had better not forget Mother's Day, even if massed space armadas are about to rocket into battle across the galaxy. The great and powerful White Wizard had better remember what his mom told him about washing his white robes separately from his colored long johns. Speaking of washing, who do you think taught that famous alien to scrub behind his pointy ears? And as for that muscular barbarian swordsman - with all those mighty hews, why can't he clean up his room? Enough about the square-jawed steely-eyed heroes of science fiction and fantasy, already, where would those heroes be without their mothers? It's time to give the mothers of the galaxy their due.
