. . . when watching The Adventures of Rocky & Bullwinkle, in one of the “Jet Fuel Formula” episodes, when Rocky & Bullwinkle are aboard the moon men’s ship, Rocky is reading from a Rocket Cook Book, and one of the moon men . . . it might be Gidney, or then, too, it might be Cloyd . . . no, it turns out it was Gidney . . . pulls the book Earth from a shelf (to ascertain where on the planet mooseberries may be found).
Another volume on that shelf bears the title Sex on Planet “X” on its spine.
