Have you ever gone to a website, it loads, and then you immediately start to try and click away but can't find the back button because the websites awfulness has blinded you? Of course you have, and once you finally make it back to your safe place, you realize that you can never get the image of that hell out of your head. Take this website for example: http://theworldsworstwebsiteever.com/
Warning: you may scream in terror and pull an Oedipus Rex. (Stabbing your eyes out, not marrying your own mother. Sicko.)
Anyway, the people who created this monster (it just wants to love and be loved) did so for educational purposes. They did everything you were not supposed to for website design, and they did it well (or horribly). So, if you ever make a website, you will now always have this in your mind as a reference of what not to do.
