Playboy supports open source..

Interesting mirror to download your open source software. If you go looking for stories, pics or centrefolds to http://mirrors.playboy.com/, then you'd be sorely disappointed. Actually, it is an unsupported mirror for open source software like FreeBSD, Apache, Fedora and the Mozilla suites. It is also an official mirror for Firefox and Thunderbird.

Turns out, that in fact, the Bunny corporation uses a lot of open source software for its daily operation. Its proved cheaper and has vastly improved performance. Hence, mirrors is just a small symbolic token of appreciation towards the Open Source community.
