From Hippo Eats Dwarf by Alex Boese, who claims only one is a hoax:
Page 32: Japanese women can purchase a breast-enlarging ring tone for their mobile phones. Its inventor, Hideto Tomabechi, promises the ring tone will "increase the breast measurements of those who listen to it." Just how is unclear. The ad copy states only that "it's a technique involving subliminal effects." I've had the good fortune to hear the ring tone, and it sounded like an extended Jimi Hendrix guitar riff. So far, I have experienced no breast development.
Page 59: Does a cell phone accessory project a high-intensity electromagnetic sound cone, inaudible to the human ear but fatal to sperm cells, thus serving as an effective means of birth control when placed nearby during moments of intimacy? The Belgian company Prophy-Lectic debuted the Nippit 3000 mobile-phone birth control accessory [in 2004].
