We're not sure whether Julia Louis-Dreyfus is angling for a "guest actress on a talk show" Emmy that doesn't exist, but she's certainly put in game performances over the past week, whether she's enlisting in the Letterman/McCain War or stealing from Tina Fey on the advice of a mischievous Conan O'Brien. Louis-Dreyfus's latest target was The Ellen DeGeneres Show , and she smoothly changed promotional gears to talk about the newest storyline on her sitcom The New Adventures of Old Christine , which finds her character entering into a gay marriage with Wanda Sykes to help the latter stay in the country (even though immigration is a federal issue that California's same-sex marriage laws can't circumvent). Naturally, Ellen had a few Prop 8-related words to say on the subject — though, Ellen? Money talks , too. [The Ellen DeGeneres Show ]
