First, it was awesome how terrible she was on NBC's live Peter Pan, I haven't gotten that good a laugh at NBC programming since Seinfeld was on the air. I watch her on the HBO show 'Girls', and she's a half decent actress, but the peter pan musical was so bad it was epic.
In regards to Brian Williams, I don't really consider him a journalist so I have no problem with him letting the lie go on so long. His job is to read the news people hand him, and he does it well. If I expected more from him, I would be upset about the lying.
