Via waxy.org: Remember the church sign generator? In a previous post here there is a link to the web site as well as a link to a collection of funny fake church signs created with it.

Well, the site's creator noticed that he was getting a bunch of links from a prominent racist web site. He then set it up so that whenever someone clicked through to the church sign generator from the racist web site, the fake church sign says "RACISM SUCKS", regardless of what they enter. His blog post is here.
