Harold Camping was an American radio broadcaster, and author. Camping was notorious for issuing a succession of failed predictions of dates for the the second coming of Jesus Christ.
I'd like to personally challenge Mr. Camping to act with integrity on May 22, 2011. On that date, it will be refreshing to hear him publicly and undeniably say that he was wrong. I've extended the same challenge to other would-be prophets with little success, so I'm not going to hold my breath.
