Even since John McCain announced his vice-presidential pick, there's been buzz about how much the bookish barracuda resembles one Miss Liz Lemon. Today FishbowlNY reports: "A reporter asked Lorne Michaels about the possibility of Tina Fey returning to play vice presidential candidate Sarah Palin. 'This Saturday or ever?' Michaels asked before saying, 'We had something on Sarah Palin yesterday at read-through but with the Charlie Gibson interview tonight, things will change again.'" He added: "There are discussions. They are ongoing." Yeah, yeah, we get it, no promises. Kristen Wiig, however, we're still holding you to yours. [FishbowlNY/Mediabistro]
