This one was interesting. The Obama campaign started this thing where they were encouraging people to put their hands together to make an "O" with their hands...they would wave it over their heads at rallys, or "flash" it to someone else to signify that they supported "O".
Even as brain damaged and sheeplike as his supporters are, even THEY realized how creepy it was, and it never took off.
When I heard about this and saw the graphic they put out to demonstrate it, it immediately brought to mind the famous "Head up Ass" image out there in Internetland...and I immediately made a morph...:)
I had one guy who was horrified and said when he first saw it, he thought I was morphing it into Goatse...
