Demi Moore -- Flyin' Solo at Sarah Silverman's Comedy Show

With no Ashton in sight, Demi Moore hit up Sarah Silverman's comedy show in L.A. Thursday night with some friends -- and she even brought her wedding ring along for the ride.

One source at the show tells us Demi appeared to be having a good time -- laughing and hanging out ... "like a regular person."
