I'm going to be watching this show on tape every week from now on in. Fast forwarding over Paul Merton's pointless and laboured small-talk makes it a much better show!
I enjoyed this week more than some previous. As is said above, Rufus did a great job - really getting into the part. I think the key was rather than just answering the questions the ensemble put forward, he took control of the scene (e.g. flirting at one point).
Richard Wilson also did this rather well in the mini-cheese sketch. When he started ignoring the questions and back-chatting the 'diners', that's when I actually started laughing-out-loud.
