Take one axed budget, one eager creative team and one set of parents willing to let their five-year-old twins curse on-camera and you have "Bollocks", Volkswagen's Kinsale-winning viral campaign that's making the rounds on-line.

Not officially endorsed by the auto maker (it's only available as an e-mail attachment), the test spot, created by Dan Hubert and Amber Casey at BMP DDB, London, consists of a series of vignettes of a child going about her day-to-day life uttering: "Bollocks!" when things don't go her way - for instance, when she's sitting on the loo and realizes there's no toilet paper.

Finally we see her dad filling up his Volkswagen at the gas station. Suddenly he realizes he's putting gasoline into the car instead of diesel fuel and yells: "Bollocks!" It's then that we realize where she gets her potty-mouth.

The tagline: "VW. Don't forget it's a diesel."

Already praised by the Daily Telegraph and earning a Gold award at last week's Kinsale fest for newbie director Jackie Oudney of Bliss Films, "Bollocks" was written in response to a brief for VW diesel. Then they cut the budget, but BMP still wanted to make the spot.

Hubert and Casey hawked "Bollocks" around several production houses, got Bliss interested and "made it for nothing," says Hubert. They picked Oudney because "we liked her execution, and we wanted a female touch. She was amazing with the kids - she made them relax and brought out the best in them."

To train the twins to say the word 'bollocks' during the two-day shoot took place in Queen's Park, north-west London, Oudney got them to splatter paint on canvases and repeat the name "Jackson Pollack".

How did the twins' parents react? "They were quite cool" about the swearing, Hubert says. "Apparently they haven't said the word 'bollocks' since -- they've got it out of their system."

BMP produces about four spots per year for VW, Hubert estimates. This is the first viral campaign but it's not yet running on VW's web site a la Ford "Evil" campaign.

Hubert says the client likes the spot but fears it's too risqué for a TV or cinema release. Internally, too, "there were a lot of scared people in account management, but we just thought: 'bugger them'."

While still hoping to sway the auto-maker toward a national cinema/late night TV rollout, Hubert is philosophical. "If we can't run it in Britain we'll run it in Australia or somewhere where they're familiar with the word 'bollocks'."
