It's a strange sort of television programme.

Each installment is around 10 minutes long and is primarily made up of Dan and Becs each talking into a video camera, finishing each other's sentences and shedding light on their differing perspectives of their relationship. It's funny, quirky, likeable. Dan is an uncertain sort, concentrating on his 'art' of filmmaking which sees him back on the dole.

Becs is a struggling model/actress with a network of friends whose names echo those yelled by irate mothers across the floor of Dundrum shopping centre.

Oddly, in real life, it's difficult to see where art stops imitating life, and vice versa. Coffey is clearly a nicer guy than the rudderless and selfish Dan. White is endlessly chatty, a little self-conscious and very funny. They're both a bit posh. Or at least they sound it.

In the latest series, the characters are "probably a bit more serious", according to Coffey. Dan has returned from a 'finding himself ' trip to South America with natty hair and a decision that he is truly in love with Becs and completely committed to her. "But as a result of that, he becomes a bit more clingy and annoying, " Coffey says. "Also, they've been going out a long time now, " White interjects. "It's not just a new romance and I think you definitely see elements of that and slightly more serious problems, " they both laugh.

"Such as the dilemma of living at home when you're going out with someone, " says White. "Which prompts Dan to move out, which causes more problems, " adds Coffey.

Perhaps they've spent too much time filming, but Coffey and White really do finish each other's sentences just like Dan and Becs. Chatting to them is like watching and trying to keep up with a game of table tennis. Albeit an entertaining one.

They were both surprised with the success of the first series, and the coverage it garnered. It's difficult to see what Coffey's main aim was when he set out to write it. He says he wanted a TV show about a couple and would draw on his experiences in south Dublin to make up the context. But when RTE started pushing the programme, advertising it endlessly, it took off.

"I think they thought it was going to be the Ross O'Carroll-Kelly thing, " White says.

"And a lot of people, I remember reading some of the blogs and people saying, 'Oh God, we're so sick of this.' But I suppose because it was the first show about that kind of Dublin, people just assumed it was going to be Ross O'Carroll-Kelly and I was going to be Sorcha and he was going to be Ross."

What transpired is a more complicated, less exaggerated insight into a couple who are more obsessed with themselves than each other.

But as both characters admit to drawing from their own experiences, backgrounds, stories from friends and other anecdotes, where do Dan and Becs end and Dave and Holly begin? The lines seem to frequently blur. This confusion is all deliberate, according to Coffey. "I wanted people to switch on and maybe for a few minutes to go, 'Are these guys for real?'" "Some people really did think it was real, " White laughs. "Because we each have Bebo pages and what's great is, I think it's about episode six or seven, he mentions it and suddenly everyone was online and communicating with us. So many people thought it was real, they genuinely thought I was Becs and he was Dan and we just decided to video our lives and put it up on TV as you do and they genuinely thought it was completely real. I was getting messages going, 'Big mistake to mention your Bebo page on live TV, '" she says, cracking up.

"You just sort of think 'oh dear'. But then you go on to their pages and realise they are versions of the Becs and the Dan." They talk further almost amongst themselves about how they drew from their own lives to create story lines, even though they both mixed in different circles, despite from being from "around here" (Dalkey) and White now living in London. Like Becs, White dropped out of college and had a bit part in Fair City. "My voice is an accident at birth. And, you know, you can't deny that. But it just adds more realism to the show I suppose."

"Dan is evil. He's the evil half of me, " Coffey decides. "If I wanna think about what Dan would do, I just kind of go into the worst place in my head. Dan's what I might have turned out like if I'd had different family and friends, different people influencing my life. Although that doesn't explain Dan because he seems to have quite nice parents and still turned out bad. Maybe his friends are all dickheads. . ." he trails off.

"I think Becs is kind of similar to me. That's what we came up with in the beginning. I had dropped out of college, so she had dropped out of college. Some of the lines were from actual situations in my life, " White says, before being challenged by Coffey: "You're smarter than Becs though."

We hop into the photographer's car, maneuvering the baby seat which prompts Holly to talk hilariously about her goddaughter and her apparent failings as a godmother. "I just want to parade her around town, " she exclaims, before delving into the merits of being able to play with a baby and then hand it back. Driving down to the small harbour opposite Dalkey island, they motion to a friend's house near Bono's and talk about a recent 21st party related to it.

For the photograph, Dave apes a purposely cringey pose, pretending to skim a pebble off the surface of the sea and follow it up by putting his hand to his forehead and gazing into the distance. "Do that again, " the photographer shouts from his vantage point.

"No f***ing way! Are you f***ing kidding me?" Dave yells from the sea below. "So cheesy, " he sighs dramatically.

There are rumours that a bigger career move for White is in the works. Her recent birthday party at Eddie Irvine's bar Cocoon in Dublin, seemed, according to some people, to double as a going-away shindig. "She's in LA at the moment, isn't she?" an RTE presenter says to me a couple of days ago, followed by a swift, "Oops, I wasn't meant to say that." First up, though, is her completion of a journalism and media degree in London.

Coffey has submitted a further couple of ideas to RTE. On the way back into Dalkey, White hops out . . . she's going to call into her mum's shop. Coffey stalls for a bit to chat to the photographer and with a polite thumbs up, a smile and an instruction to enjoy the Electric Picnic, he's back into his real world.
