American radio preacher predicts doomsday

If Harold Camping is right, then you should probably stop reading this and go say goodbye to your family.

The 89-year-old California-based preacher host of the "Open Forum" television and radio show has predicted that the Christian Rapture - the return of Jesus Christ and an accompanying worldwide disaster - is set to take place on Saturday, May 21.

"We have no plan B, it is going to happen," Camping said. "The Bible is a very factual book."

Camping has, according to some of his colleagues, spent millions of dollars promoting the end of the world, but he predicted a previous Rapture in 1994. Clearly, that didn't happen.
