Just saw the latest episode of Larry David's HBO series, "Curb Your Enthusiasm" which I think is not only the best comedy on TV but the only one I can even stomach. To me, this show is everything the Michael Richards show is not.
Any way, at the end they showed a preview of next week's episode and Julia Louie-Dreyfus is guest starring in it. Looks like she plays herself and has a fairly big part from the preview.
The series airs on Sunday nights at 10PM (9 central). Occasionally I see re-runs showing throughout the week.
