Mark and Jeremy compete for the attentions of their attractive neighbor Toni.

Mark wants Jeremy to get a job in the same office as him so he can pay his share of the rent, however Jeremy isn't keen on the idea. Mark also worries whether Sophie, a co-worker he fancies, may or may not think he's a Nazi.

Mark begins to forge a partnership with his idol, business guru Alan Johnson, and begins to change his behaviour to be more like Johnson. Meanwhile, a displeased Jeremy tries to think back to "the bad thing" he did with Super Hans in a drug-heavy weekend.

Mark is angry at Sophie when she gets promoted for a job instead of him, when she told him she wasn't going to apply for it. Jeremy gets a job at a recording studio, which results in Super Hans having an affair with Toni after he brings her in in order to impress her.

Jeremy runs into an old acquaintance from school who he used to pick on but has become successful now and hires Jeremy to make a soundtrack for a film he's making. Mark makes a new friend at work who turns out to hold a fair amount of prejudice. Meanwhile, Sophie spends time with Jeff.

Mark meets a girl called April working in a shoe shop with the ideal combination of good looks and low self esteem, and when he returns to see her again he discover that she has gone back to university, which happens to be the same university he and Jeremy went to. And Jeremy is also going there to do a gig with a band, so they both take a trip down to the university. Mark pretends he's signed up to the same history course as April in order to see more of her and begins to shine in his knowledge of the subject matter.

Jeremy agrees to marry Nancy in order to make her eligible for a visa, and whilst she insists it's purely an administrative procedure, Jeremy's sure it will be the happiest administrative procedure of their lives. Mark is pleased to see Sophie and Jeff breaking up but finds it hard to make his move and ends up being set up on a date with another woman. A jealous Toni starts an affair with Jeremy.

Mark and Jeremy's old friend Merry, who doesn't seem to be in the best state of mind, gives Jeremy and Super Hans ownership of a pub, and Super Hans has some very radical ideas about how to run it. Meanwhile Mark's relationship progress with Sophie is stunted when she has to start working in Bristol.

Jeremy hopes to hold a magic mushroom party in the flat whilst Mark's away for work, but Mark's illness complicates things, and so Jeremy must find some underhanded way to keep him out of view for the duration of the party.

Mark takes Sophie away for the weekend with the idea of proposing, but finds things don't go as well as he hoped as he and Sophie don't have that chemistry. In the same hotel, Jeremy has trouble getting rid of a rehabilitating Super Hans so that he can finally hook up again with old flame Big Suze.

Mark still hasn't gathered together the courage to dump Sophie, something that proves a problem when they go to the country to meet her parents. Worse, he makes the mistake of inviting Jeremy along. Cue a weekend of gunfire, infidelity and arson.

Jeremy is thrilled when one of his musical heroes, The Orgazoid, employs him as a general handyman - but just how "handy" will he have to be? Mark attends his old school reunion disco and finds himself falling for old crush Sally Slater once more. But with her a bored housewife, could an affair between them really happen? If Mark can conceal from Sally his own impending marriage.

It's the day of the big wedding and Mark is desperately looking for a way out of going through with it - but he's determined not to be labeled a jilter at any cost. Jeremy still harbors hopes of winning Nancy back, but being Mark's best man keeps getting in the way.

Mark and Sophie both return to work after their disastrous wedding day, with Mark determined to "Mandleson" her in proving who should get all the blame. His only sympathizer is new IT girl Dobby, who's looking for something far more adventurous than a USB stick in the stationary cupboard. Jeremy and Super Hans rope Sophie's nephew Barney into their band when they realize he's actually got some musical talent but their gig is destined to end in disaster when Super Hans goes too far with seeing how far they can push Barney.

When Jeremy's aunt dies, his mum agrees to give him half the inheritance to the tune of £20000. But his mum's new boyfriend, Martin, believes Jez needs to be taught how to use money properly and so his money will be governed by Mark. Martin's seemingly lesbian daughter Natalie takes a shine to Mark, when he begins working on her father's memoirs - and she won't take no for an answer.

Jeremy and Super Hans are thrilled when super-confident Cally agrees to be their manager, but less so when it turns out they're playing at a Christian rock festival. Mark, under the belief that Cally is "the one", joins up as roadie and finds her quite susceptible to his dubious charms. But when she decides Jeremy is holding Super Hans back, Mark has to decide between his new lover or his best friend's happiness.

Mark's promotion bolsters his confidence, he's getting closer to Dobby through a shared love of fantasy role-playing game and Sophie's ready to annul their marriage - but a drunken one night stand has life changing consequences. Jeremy decides that his life is going nowhere and joins a cult, which gives him a new outlook on life completely. With Mark and Jeremy's lives moving in different directions is this really the end of the El Dude brothers?

Jeremy starts working at JLB Credit, however the entire UK division of the company gets shut down by the German head office the same day. Mark forms a group to protest against the firings but really wants to impress Dobby.

Mark invites Dobby to a party at his flat, then has to work out how he'll actually organise it. Meanwhile things have gotten a bit frosty between Jez and Elena but he reckons he knows to handle it so she'll come running back to him.

After Gail's surprise proposal to Elena, they are soon to have a civil partnership, but Jez won't give up that easily. Sophie is also due to give birth and wants Mark to pass his driving test, unfortunately he gets a bad driving instructor.

Sophie is in hospital in labour and Mark isn't really sure how he can be of help. Jeremy starts fancying a girl he meets in the waiting room, however she isn't quite 100% available.

After discovering Dobby has a boyfriend, Mark and Gerard become allies in a "Dobby club". Super Hans joins a band and Jez is excluded, but tries to get the upper hand through his new job with a record label owned by Zahra's boyfriend Ben.

In his efforts to impress the pretentious Zahra Jeremy decides to host a book club for her and her friends in his flat though disaster strikes when it becomes apparent that he has never read a book - apart from 'Mr Nice'. Mark meanwhile battles with Kenneth in order to gain the favours of Dobby but finds that he might need some help after all to satisfy her.

Mark has his family over to the flat for Christmas dinner, as well as Dobby, who he is finally going out with, except he hasn't told his parents yet.

It's New Year's Eve. Mark wants to find Dobby and sort things out between them, Jeremy just wants to have a good time. However newly-single Zahra has invited Jeremy to move in with her.

A month has passed. Dobby has still not said that she will move in with Mark and Jeremy has not said he will move out. Mark invites Dobby round to share a pizza and watch 'The Apprentice' but unfortunately Gerrard, her other admirer, dies of the flu that evening and Dobby feels guilty for not being with him. Jeremy decides to undergo therapy which, after an inauspicious start, he loves. Mark goes for a job with a bathroom fittings company but the final interview clashes with Gerrard's funeral so he has to make a brief oration before leaving. At the wake Mark again asks Dobby to move in with him but she says there is no need as she is now an independent woman, thanks to the money left her by Gerrard.

Now a big name in bathroom sales, though annoyed that Dobby has a new job in I.T., Mark writes a book, entitled 'Business Secrets of the Pharaohs' and even finds a publisher in Greg, who meets him at a refreshment stand. However Mark is told he must foot half the publishing costs. Jeremy decides to be a life coach and goes on a week's course but is the only candidate to fail - largely because he made such bizarre sexual demands of course leader Celia - though he does work out that Mark has been conned by Greg.

Simon,Dobby's ex-boyfriend,asks Mark,Jeremy and Super Hans to join him on the paint-balling day Dobby has bought as his birthday present. Simon puts Dobby and himself into the opposing team to Mark and Jeremy,leading Mark to believe it is all a ploy to win Dobby back. Dobby and Jeremy bond over a joint but Mark is stuck in a bunker with a stoned Hans. When Hans makes a break for it and aims his paint-gun at Dobby Jeremy gallantly steps into the line of fire to take one for her.

Jeremy agrees to move out of the flat and share with Super Hans but Dobby would prefer to go inter-railing across Europe than move in with Mark. To make things worse for Mark not only has Hans been promoted above him at work, making him Mark's boss but Jeremy has arranged for the unstable Big Mad Andy to decorate the flat - largely so that Jeremy can sign him up for life skills coaching. Mark finds solace in an MBA evening class, meeting the elegant Stephanie and Jeremy, strangely in love with Dobby, urges him to pursue her but Mark cops out when he gets a call from Jeremy requiring his help to calm down Big Mad Andy.

Jeremy is moving again, to stay with Mark's sister Sarah and her five-year old son Joshy, for whom he is something of a toy. Despite Jeremy having taken all his chairs Mark hosts the residents association for the flat block and is elected chairman - though he does use the funds for his own repairs. On the down side he is less successful as a taps salesman despite Jeremy's efforts to help and Dobby tells him she will not be moving in with him. He will not be alone though, for, having had enough of Sarah and surviving an uncomfortable night at Big Mad Andy's, Jeremy returns to the fold.

Mark is hoping Dobby will move in with him so Jeremy has to move back with Super Hans,who stays up all night and keeps snakes. Dobby has a job offer in New York from ex-boyfriend Simon so Mark decides he and Dobby should have a picnic in the country where he can declare his feelings for her. Sadly for him Jeremy,who is also in love with Dobby,turns up as well,leading Dobby to believe that they are gay as they are so inseparable. The two men start to fight over Dobby only to discover she has gone. Later she texts to say she is heading for New York.

With Jeremy still refusing to apologize for falling in love with Dobby, he and Mark are still not on speaking terms six months later. However, the two must put their differences aside to celebrate with a newly-clean Super Hans.

Mark is uncertain about being best man at Super Hans' wedding, until he discovers Dobby is invited. Meanwhile, Jeremy's life coaching career is taking off but leads to a surprising encounter.

Though April is back with husband Angus Mark still pursues her, taking drugs with her but unwittingly attracts Angus as a friend. In order to impress Joe that he is a life style coach Jeremy rents expensive office space but regrets it when he sees the interest he must pay Mark for the loan and colludes with Super Hans to rob Mark's bank. When the robber backs out however Mark rather wishes he hadn't.

Dumped by April Mark prepares for a day out with son Ian though Ian's mother Sophie is more concerned with current boyfriend Duncan's infidelity and wants Mark back. To complicate matters April also changes her mind. Super Hans and Jeremy argue over who should get the royalties for a song they wrote in the 190s with Hans winning, Jeremy taking a pitiful and dangerous revenge at a children's play area.

Jeremy is worried about turning 40 and Mark is running out of time to win over April. How is it all going to end for the El Dude Brothers? Are they going to be alright?

Simon,Dobby's ex-boyfriend,asks Mark,Jeremy and Super Hans to join him on the paint-balling day Dobby has bought as his birthday present.
