Despite being bullied on the street by the local children, Mark (David Mitchell) sets himself the task of sleeping with the divorcee Toni (Elizabeth Marmur) next door, basing his seduction technique on the Battle of Stalingrad. But part of his plan includes humiliating his flat mate Jeremy (Robert Webb), who vows revenge. Includes scenes of raw meat being placed in a bed.

Jeremy (Robert Webb) and Super Hans' (Matt King) band, the Hair Blair Bunch, is going nowhere so Jeremy reluctantly agrees to go for a job working in Mark's (David Mitchell) office. And Mark's attempts to flirt with Sophie (Olivia Coleman) backfire when he accidentally leads her to believe that he's a Nazi.

Mark and Jeremy go 'on the pull' and find themselves smoking pot in the Lazerbowl toilets with a teenage goth. Jeremy perseveres with the sexy Toni despite her refusal to stop talking about Peter Gabriel, and after a few pints Mark decides a melon is a big improvement on a bowling ball.

Mark makes a friend at a business conference but will it turn into more than just friendship? Jeremy is forced to consider Super Hans as a replacement flatmate and resolves to stop at nothing to keep he and Mark, the 'El Dude Brothers', together.

Jeremy tries to wow Toni with his new job in a music studio while Mark gets passed over for promotion in favour of Sophie, and goes slowly round the twist. Each tries to solve the other's problems with the help of phone stalking and pepper spray.

In the last episode of the series, death and terminal illness prove to be the keys to romantic success for Mark and Jeremy. Jeremy gets in with the Christians while Mark finds the perfect venue for a first date with Sophie - a funeral. Everyone's having a great time until the paramedics arrive.
