Exasperated after a string of bad dates, Catholic martyr St. Jude vowed Monday never to respond to another personals ad. 'Man, talk about hopeless causes,' the holy figure said. 'Do I have a sign on my head saying, 'Losers of the world, contact St. Jude?' I mean, these were some big-time desperate cases.' Jude added that, from now on, he will respond only to direct prayer delivered in a Roman Catholic Church.
