Armchair epidemiologist and former decent actor, Charlie Sheen, spent a portion of Monday night in a Los Angeles emergency room with a “severe case of food poisoning,” says his publicist Jeff Ballard.

“It was clams, bad clams,” adds Ballard. “Nothing too exciting.”

Given Sheen’s penchant for porn stars, bad clams could mean anything.

The former Two And A Half Men star had dinner [a seafood pasta dish] delivered to his house last night and started “feeling sick” a few hours later.

“Just to be on the safe side, he went to the hospital,” says the rep. “They checked him out, hydrated him and sent him on his way. He was back home in bed 90 minutes later.”
