Murderer-developed file systems introduce new features

Hans Reiser, the software engineer who developed code for the Linux operating system, wasn't just convicted of first degree murder in the disappearance of his ex-wife. He's also become the butt of an incredibly obscure joke. Someone edited a comparison of file systems to add a new feature to ReiserFS and Reiser4 — unlike any other file system available today, the two developed by Hans Reiser will "Murder Your Wife." The change was removed from the Wikipedia page within 90 minutes.
