I'm still betting on talking dogs and zombies, plus whoever will collaborate with them. That seems to be the most likely scenario.
Preacher Harold Camping is leaving it to the Mayans. The 90-year-old head of Family Radio incorrectly predicted the Rapture would take place on May 21, 2011, and when that didn't happen he aimed for Oct. 21, 2011, which also failed. "We have no new evidence pointing to another date for the end of the world," Camping said in a statement on the Family Radio website. His bad timing on the Rapture became a huge media event, mostly to mock him, but some of his followers quit their jobs and donated their life savings ahead of the event. Camping said he has sinned by promoting May 21 as Judgment Day and says he has no plans to ever predict the date again.
