The pair picked up the award for their spot for BT's 118 500 directory enquiries service. The runner-up in the awards, judged by Euro RSCG London's creative directors, Olly Caporn and Dominic Gettins, was "train" for Yellow Pages from the Abbott Mead Vickers BBDO team of Peter Soutar and Mary Wear.
Drugan and Friedburg's ad for BT, "vocoder lady drink", features a man who is so obsessed with a female automated voice that he asks her out for a drink.
He then professes his love for her, only to receive the automated message "Sorry, I didn't quite catch that" as a reply. The ad ends by reminding listeners that BT's old 192 service is now only available through the 118 500 number.
Commending the winning ad, the judges said: "So often, radio ads fail to be melded to the brand they're advertising - this one couldn't have been for anything else. A man and his unrequited love for the female automated voice on the other end of the line. Original, funny and memorable."
The Aerial Awards, held in association with Campaign, are judged each month, with the winners put forward for the annual award, held on 26 October at the Bloomsbury Theatre. Malcolm Poynton, Ogilvy & Mather's executive creative director, is chairing this year's nomination panel.
