It's great to see the Muppets in use so much and Bill's Rowlf is really good and can only get better, seriously; that was the best bit of the whole episode, I hope we see more and more of him.
The downer? Not very funny, actually; not at all funny, some of the jokes didn't even make any sense either; "Once you go orange you never go back"? Huh?
So all in all, good performances but the writing needs some improvement.
