Their 15 minutes of fame may be up, but some former "Survivor" cast members can't seem to steer clear of infamy. Long after the cameras stopped recording their bug-eating and backstabbing adventures in some exotic locale, a few alums of the CBS reality show keep making headlines for the wrong reasons. In May, a former "Survivor" champ was sentenced to federal prison for not paying his taxes. Another former winner was suspended from his job last month for cooking up lies to go on an overseas "Survivor" promotional tour. And just two weeks ago, yet another ex-champ was busted for shooting a puppy. It's proof that surviving in the real world is no sure thing for these reality TV has-beens. Famous for lumbering around a Malaysian island in his birthday suit on the first season of "Survivor," Richard Hatch now has to wear a prison jumpsuit. The original reality show schemer - dubbed the "fat, naked guy" - was sentenced in May to four years in prison for trying to dodge paying taxes on the $1 million prize he won in 2000. After being memorably labeled a "snake" by angry truck-driving castmate Susan Hawk on the show's finale, Hatch was slapped around even harder by prosecutors at his sentencing. "Our nation's federal tax system is not a reality show to be outwitted, it is a reality, period," said Eileen O'Connor, an assistant federal prosecutor. After winning $1 million in 2004 on "Survivor: Vanatu: Islands of Fire," Chris Daugherty went back to his $34,000-a-year job as an Ohio highway worker. But last month, he was suspended without pay for 20 days after going on a phony sick leave, and instead taking a "Survivor" promotional tour of Europe. Daugherty had claimed he needed time off to fight stress. Previously, he had filed a rejected request for military leave, since the tour was visiting a German military base. "What would George Bush think of the Ohio Department of Transportation giving me a hard time to support our troops overseas?" Daugherty said. But the 35-year-old took the controversy in stride. "I survived Vanuatu," he said. "I'll survive ODOT." Brian Heidik aimed high and won "Survivor: Thailand." Then he aimed at a puppy and landed in jail. The 38-year-old Georgia man was arrested July 4 after allegedly shooting a mutt named Edward with a bow and arrow. Heidik, who conquered the reality show in 2002 and once appeared on "Baywatch Nights," also has been in trouble recently for allegedly shoving his wife in the face. Fame - or whatever winning "Survivor" amounts to - hasn't been kind to the family, his wife told the Atlanta Journal-Constitution. "I think maybe it's the show," Charmaine Heidik told the newspaper. "I don't think he's ever adapted to real life since then." Jenna Lewis wasn't one of those "Survivor" sexpot contestants who posed nude - though there have been a few of those, too, such as Jenna Morasca and Jerri Manthey. Instead, the leggy Lewis made an X-rated wedding-night flick in which she and her new model husband steamed up the computer screen for 42 minutes. Supposedly recorded for the couple's private use, the allegedly stolen tape popped up on the Internet for $40 a pop. The mother of twins cried, then issued a press release saying she was "fighting mad." But as Daily News columnist Ben Widdicombe revealed, her tears might have been of joy. Sales of the tape netted more than $100,000 - with Lewis reportedly pocketing 70%. Things got worse for Lewis, too. After just a few months of marriage, she split from the husband who happily showed off his washboard abs and a whole lot more on video. But at least they'll always have video memories. jmartinez@edit.nydailynews.com
