Foster's Lager has a new installment for its "How to Speak Australian" campaign. The first of three TV spots from WPP Group's J. Walter Thompson, New York, targets a more sophisticated import beer drinker. "Keeper" shows a nervous man whose beautiful date puts him at ease by topping off his beer and smashing the empty Foster's can on her forehead. The ad debuts today; the other two spots break in April. The campaign also features print breaking in May issues of Maxim, Spin, Playboy and ESPN The Magazine, as well as radio spots breaking April 4. Copywriter: Jeff Martin. Creative director: Dan Bruce.
