A man who shelled out his life savings to tell people about the end of the world, spent the evening of May 21, 2011 being heckled and peppered with questions about why his predictions did not come true.

Robert Fitzpatrick, a retired MTA employee, said he spent $140,000 on placards on subway cars and bus shelters around the city warning people to repent before their time on earth was up.

Last Saturday evening, at about the time Fitzpatrick predicted the rapture would begin, he found himself hounded by detractors and members of the media as he stood in Times Square.

"I see that we're still here. I don't understand it," Fitzpatrick said. "I don't understand why nothing has happened."

One hyper-aggressive agitator kept asking whether people's donations they gave to help warn of the end of days would be returned. Fitzpatrick said that money had already been spent. Another woman claimed that she had given Fitzpatrick money to help spread the word that the rapture was near, but Fitzpatrick denied those claims.

Hecklers' rage against Fitzpatrick may have been misdirected. As one YouTube commenter put it, "Geez, bro, take it easy on the guy. He's totally penniless now ..."

Fitzpatrick and thousands of others believed religious figure Harold Camping's prediction that the world would end on May 21.

The California preacher did not release a statement after the non-event, but one of the board members of his Family Radio International organization said Camping was "mystified" and "a little bewildered."

As for Fitzpatrick, it would seem that his conviction held strong until Saturday evening, since he spent it in the middle of Times Square where he could easily be found and swarmed if, as it happened, he was wrong.
