I just watched the sketch on the SNL website and I was sort of mixed.
Towards the middle, I was getting a little mad at the fact they ran over someone and that Animal had dynamite and drugs on the bus. And I have no clue why Nipsey Russel was on the bus; he didn't appear in The Muppet Movie at all! Of course that must have been the writers decision but I found that pretty weird.
However, I liked Fozzies (Jason Sudekis) joke as the gang gets pulled over: "We're screwed!" he says as he holds a screw in his hand.
In the end, I like the sketch but at the same time I felt a little angry at the writers and maybe at Seth Rogen. Does he like the Muppets for some reason? Because I don't know.
