Absolutely love peep show, been my comfort rewatch show for so many years now but never get sick of it. Love so many of the moments already mentioned but two of my faves has to be -
"You don't perhaps wish to play the classic board game, sorry? Or we could hunt for youtube clips of the Ronnie Corbett sitcom 'Sorry!' while we ate some..." (bit much) "...Sorrel soup?" and "Alright, you've had your fun with the sectioning. There'll be no more sectioning today"
