And the Oscar for most mouthwatering accessories goes to: Sandra Bullock. During the Joan Rivers preshow, the actress had dapper costar Hugh Grant on one side and…Listerine PocketPaks breath strips on the other. ”It was a total surprise,” says a Listerine spokesperson of the impromptu TV appearance. ”We sent samples to be handed out — as we did at the Golden Globes and the Emmys — but we hadn’t had that experience, so we were shocked.” The cellophanelike strips were invented by Pfizer Consumer Healthcare. A rep for the actress would note only that ”everyone was chewing on them,” not just Bullock. Yes, but Sandy will be getting a care package.
