When I was a kid I couldn't figure out how video got to a TV through a tiny little cable, and with so many channels! I figured that a huge set of tiny images must be transferred through the cable using fibre optics or something (like a multiplexed image), and then the TV would pick a section of this big image when you choose a channel, then magnify that section onto the TV screen and voila - TV! I figured the sound was picked up using some sort of radio tuner. I was tempted to cut the cable and see if a bunch of tiny images would project from it! I understand how they work today, but you gotta admit, it's pretty amazing how color video goes through a simple 2-pin cable.
