Dave Barry in Cyberspace
"We know that if we turn on a radio, it will start producing sounds, such as the song 'Wooly Bully' by Sam the Sham and the Pharaohs. If we were pressed to explain this, we'd probably parrot the explanation we got from our science teachers, which is that the radio is receiving 'radio waves'. But the truth is that we have *no idea* what this means.... The pathetic truth is that if our science teachers had told us that radios work because they contain tiny nuclear-powered singing hamsters, we'd repeat *that*, too."
