Mr Jolly introduces the vile (ie funny) Ade Edmondson and Rik Mayall characters that became the protagonists of 'Bottom': greedy, violent and stupid. What I hadn't realised until I saw the credits is that this episode was directed by Stephen Frears (as in 'The Grifters', 'The Queen', 'My Beautiful Launderette').
And, imdb tells me, Frears also directed 'The Bullshitters', which is a great Comic Strip episode. It features Elvis Costello, and it's got Peter Richardson snogging Keith Allen. Big time. ETA clip
But my favourite ever is probably The Supergrass, in which Peter Richardson looks particularly yummy and most importantly, Robbie Coltrane walks down a sea wall with a chainsaw, jumps into the ocean and saws a yacht in half. Amazing TV.
ETA clip here and worth watching the next part too
