Speaking of Classes

I have come into a situation where classes would be useful, I have function in which I could make three or four smaller functions. I think that that is how classes are used. Granted, I'll do what I need to accomplish this in a longer format, for now. But more onto the actual point of this post. Can anyone explain how to use classes, and what they are, how they are implemented, etc. without all of the techno babble that usually comes with a tutorial on classes. I have ADD, so I can't concentrate on things for very long. Part of the reason why I like to write code, helps me concentrate. But yeah, links to OOP stuff in non-techno-babble form. I know of the codewalker's tutorial, I'll hit that up at work tomorrow. But yeah, I wrote too much... haha
