Random Post page

I have a blog with a lot of posts. I think its time to put a “random” link on my site. I’d like to be able to make a page where a user can click on it. When they click that page it will take them to a random post on the blog.

Is there a plugin that does this? I don’t really want a widget that ‘displays links’ to posts, I just want a ‘random article’ link.
