When I was a kid the science channels had actual science and animal shows on them. Shows featuring Mr. Wizard showing some kid how science is cool, lions chasing down antelope on the Serengeti, weird and wonderful insects, crocodiles leaping from the water at wildebeest, etc. etc. etc. These days I've just resorted to calling Animal Planet, "Pet Planet" instead (not that I have anything against pets, I just don't need to watch a psychic communicate with a dog).
