I've been a pretty regular Saturday Night Live Fan (except for a few years in the early '80s and again in the mid '90s) for many years. I just watched Saturday's show, and had some comments I want to send along to the show. Unfortunately, the NBC Web site pretty much does not accept user feedback. So...
Paris Hilton is one of the most underwhelming "talents" of the day. She spent most of the show reading straight off the cue cards. That said, she was willing to make fun of her image, so, on the whole, she worked well as a host.
The "Fannish Phone Sex" skit was a gem. While most fannish men I've met aren't into those kinds of fantasies, the people who wrote the skit were quite familiar with the slang and made the most of it.
On the other hand, the attempted "yinzer" skit near the end showed that the Pittsburgh accent and attitude were pretty tricky to pull off. To understand a Pittsburgh accent, Seth Meyers should have listened to Dan Marino, whose yinzer accent is pretty much intact. If you didn't see the skit, Seth played a guy trying desperately to come onto Paris Hilton in a bar. Most people watching the skit probably thought he was from the south, because after he said "How'yinz doin'?" he launched into a southern accent. He went on to try to pick up Paris by talking about Bill Cowher, the Steelers coach. And he ended up the conversation by trying to give her his number, which started with "412." Now, it's true that many Pittsburgh men are into the Steelers the way that Paris Hilton is into fashion, so the skit was a cute idea. When the accents are obvious (Boston/New York/Chicago/Southern), these sorts of skits work well. But most people outside of Pittsburgh don't really understand the accent or are familiar with the slang.
