(click images) This appears to not be a joke. An online company called Cremation Solutions (based in Arlington, Vermont) is offering head urns in any likeness you'd like. Your own. Jesus. That hot chick you didn't get to bang in high school. Even the 44th President of the United States. From their website:
"Personal Cremation Urns are the latest in custom personalized cremation urns. They are created from one or two photographs with exceptional attention to details. With advances in facial analysis and the advent of state of the art 3D imaging, these high tech urns can be made to look like anyone. The full sized personal urn can hold all the ashes of an adult. For holding just a portion of the ashes, we recommend the keepsake sized personal urns. The personal urn does not come with hair. For hair we can digitally add hair if you wish, or wigs can be used." Newt Gingrich's head could hold three adults.
Why are they using Obama as their example? Maybe they love him, maybe they want him dead. Write them and ask, if you want (thanks to Catherine for the tip).
