Make way, Truthers. Step aside Birthers. Just when you thought conspiracy theories couldn't get any stupider, meet the "Brainer" movement:

Some conspiracy Web sites are claiming that the shootings that nearly killed Representative Gabrielle Giffords and did end the lives of a federal judge, a 9-year-old girl and four others never actually took place. One particularly bizarre site, run by a Texas man, says it was all a government hoax that used actors.

You know, just like they faked the moon landing, only without shooting Neil Armstrong in the head.
