Help me Internet! Random quote generator

I want to have a web page that generates a random quote from a big, largely plaintext file whenever I refresh it. This must hypothetically be easy, because many people have such a thing. But I've been banging my head on it for some time now, with no success. "Show source", which is what I normally rely on when copying other people's clever ideas, is failing me utterly. Is there someone reading this who can give me a pointer in the right direction?
