Check out this article about a true sicko. Through the Internet, he found someone willing to let himself be killed and eaten. Here is the craziest paragraph from the CNN story:

“He is alleged to have cut off part of the victim’s body before the pair ate it together. The defendant is then alleged to have cut up the victim, storing his body in a freezer and eating it over the following months.”

For an even more colorful story, read the BBC version. Yeah, don’t bother with the CNN one. Much too bland.
