It’s good to know that Ron’s supplementing his porn income these days as a human Breathalyzer.

from www.tmz.com – Despite staring down temptation that could break the strongest of men … Charlie Sheen did not fall off the wagon at a Playboy mansion party this weekend — so says, Sheen’s XXX wingman Ron Jeremy.

TMZ spoke to the Hedgehog who tells us Charlie — who recently spent some time in rehab in the wake of his Christmas Day arrest — was “totally sober” during their time in the house that Hef built.

Ron also tells TMZ, Charlie was smiling and laughing and was overall in a really good mood that night. Shouldn’t come as too much of a surprise … considering Charlie just recently scored the sweetest sentence ever for the Aspen incident involving his wife Brooke Mueller.

Then again, is it even possible to be in a bad mood when you’re at the Playboy mansion?
