The agency has drafted in 'sex and relationship counsellor' Tracy Cox - author of the cryptically titled Hot Sex - to front a campaign to make raspberries sexy.
Cox will work with 'raspberry experts' to show how eating raspberries gives you rosy cheeks, which in turn increases one's sex appeal.
The campaign, for British Summer Fruits (the industry body for soft fruits, no less) aims to increase the raspberry's attractiveness to lower income families.
'We've got to give people living, for example, in north Liverpool a reason to buy raspberries over all the other fruit they can get for the same price,' says Sputnik director Lucy Rickett.
The problem, she adds, is that raspberries are in season alongside strawberries.
So as strawberries prepare for their annual liaison with cream at Wimbledon this year, be warned. Raspberries are about to get a bit fruity, too.
