I thought Rosie's solution to the fish dots was genius, although the pen was obviously superior. Andy definitely got Greg with the fisherman line, you can see his look of fascination until he realises it was just a joke. In fact, Andy's studio lines were stupendous all episode and I was happy to see him win.
I liked "You dotted the rim" as a possible episode title - do they ever use lines from Greg or Alex or is it always contestants' lines?
Alex's joy and glee when it turned out that Jack's only attempt netted the worse possible fish was beautiful to see.
Mr Poo was more disgusting than I was expecting. The voice combined with the Nutella (I assume) was too visceral.
It was weird how the studio guest would nod as he said no.
