DIARY: Pick of the week - BMP DDB/Volkswagen

John Tylee finds BMP DDB's viral for Volkswagen diesels naughty but nice: "Years of finger-wagging at my daughters about industrial language, then along comes an ad to undermine my efforts. But you'd have to be the world's biggest prude not to laugh at such a little girl's 'bollocks' comment." The ad was written and art directed by Dan Hubert and Amber Casey. Seen better?
