WITH only one episode of “Survivor: Gabon” in the books, one castaway is already being called a weenie.

Viewers tuning in for the season premiere of “Survivor” last week got a shock when CBS did not blur video of Marcus Lehman’s penis slipping out of his shorts during a running competition.

Under normal circumstances, the network would obscure any nudity – especially given the fact that the episode was filmed months ago and presumably the slip would have been caught in the editing process.

On the episode, contestant Lehman was among a crowd of castaways competing in a footrace.

The moment, which only lasted a few seconds, has been gleefully immortalized by bloggers on the Internet.

“This was a completely unintentional, inadvertent and fleeting incident that was virtually undetectable when viewed in real time,” CBS said in a prepared statement. “In the first 24 hours after the broadcast, before freeze-frame images were widely posted online, we received one viewer comment from the 13 million who watched the telecast.”
