Agreed - that whole sketch felt like it was a chance for him to show off how well he's polished that impersonation too. Looks like Fred has a job for the next 4 years if he wants it.
As for last nights show, the only stuff I really liked was WU and the calculator sketch, the monologue was pretty alright too. That hot office girl thing with Wiig fell on its face hard, and the Vinny Vedecci one didn't feel like any of the previous versions of it. I've been unable to comment on SNL at the comedy zone board lately because I know Casey Wilson reads it, or at the very least is aware of it, and I don't wanna hurt her feelings or be that internet schmuck celebs talk about, because she seems awesome and capable of being funny elsewhere - but man, she is just awful on SNL. Awful. I haven't liked her in anything so far, and it seems the longer she is on, the worse she gets. She's just a prop with boobs.
Also, what is with all these rappers turning into Mila Kunis' character from That 70's Show? TI's song is just about his gucci rag in a club?? Yikes, maybe Trembling Eagle is right...
