That dude who's putting up all the rapture billboards for May 21 is going to feel really stupid on May 22.
From his website:
What will take place on May 21?
On May 21, 2011 two events will occur. These events could not be more opposite in nature, the one more wonderful than can be imagined; the other more horrific than can be imagined.
A great earthquake will occur the Bible describes it as "such as was not since men were upon the earth, so mighty an earthquake, and so great." This earthquake will be so powerful it will throw open all graves. The remains of the all the believers who have ever lived will be instantly transformed into glorified spiritual bodies to be forever with God.
On the other hand the bodies of all unsaved people will be thrown out upon the ground to be shamed.
The inhabitants who survive this terrible earthquake will exist in a world of horror and chaos beyond description. Each day people will die until October 21, 2011 when God will completely destroy this earth and its surviving inhabitants.
