Lisa Kudrow won the lottery today -- completing her jury duty after one day of service.
Lisa just walked out of the Los Angeles County Superior Court in downtown ... where she did her civic duty, and got the outcome everyone prays for when they report: One and done!
Lisa was not selected for a jury panel all day -- and in L.A. County, potential jurors are dismissed after one day if they're not selected.
According to our sources Lisa sat quietly in the jury pool room, and was dressed comfortably ... in smart loafers. Some of the other potential jurors were starstruck, but we're told LK was nothing but friendly.
