It was one of those rare episodes where the last two sketches to me were the funniest. I loved the NYPD sketch and I thought the Tavern sketch was funny too. Both had me really laughing.
WU joke off was funny as it always is. I liked the cold opening as well.
I thought the Southwest "ad" was funny, and so true, hahaha.
I didn't realize Jake could sing. I guess he wanted to show that off, as I think he sang a couple of times.
As for Sabrina, I agree with
@cheesesteak. She's so typical of a lot of recent female artists where the stage show trumps any musical talent. That was some of the most obvious lip syncing I've seen since Jessica Simpson!. There was one portion of one of the songs where she wasn't even moving her lips and words were coming out of her mouth. It looked ridiculous. She's another pretty face that they try to turn into a pop star. I'd be surprised that in 5 years we even remember her. But who knows right?
