I also thought it was a strong episode. Particularly liked the fanny gag and Dan's twist on Newsfox which I think it needed but now have no idea what they do with it next week. My personal favourite was the Barnsley sketch. I sent one in but that was much funnier.
FWIW I did notice not a lot of writers from Ep4 were credited on Ep5, whether that was related to the change in tone I don't know but it shows there's a lot of good competition out there.
