Last night Julia Louis-Dreyfus returned to 30 Rock last night to host Saturday Night Live, the show that gave her, her television debut. Louis-Dreyfus didn't get much air time back in the 80's when she was a castmember- the show either wasn't a good fit or show's producers just didn't know how to use her. But everything worked out fine, she went on to become a giant success on shows like Seinfeld, The New Adventures of Old Christine, and Veep. And last night's show was full of winks and nods and outright homages to her lack of success on SNL and gigantic post-SNL career, including visits from Seinfeld's co-creator Larry David, and Veep co-host Tony Hale.
