Current nutty Rapture guy has done this before.

Alleged judgment day: 1994

Ugh, this guy again. We mentioned Harold Camping in the beginning because he’s behind the current end of the world theory pegged to May 21. But he has actually predicted doom for us all before. And he has been very wrong before.

Camping published a book in 1992 called 1994?, which he claimed was the year that the Rapture would show up. Never happened. He was slick, though—when people tried to call him out, he claimed he was merely asking and that the question mark on the book's cover proves that.

Well, there’s no question mark this time around, dude. All we’re saying is we all better be dead by Sunday, or else....
