What better way to save money than sharing a bottle of mouthwash with the entire neighborhood? One homeowner takes frugality to an uncomfortable extreme, happily passing around a communal bottle in the name of saving a few dollars. While everyone else questions the hygiene of the arrangement, he remains convinced he's found a clever financial solution. Like the rest of the Smarter Way campaign, the humor comes from watching someone embrace a wildly impractical cost-saving measure while completely overlooking the obvious answer. Sure, sharing mouthwash with strangers might save a little money, but Mercury Insurance offers a far less awkward way to keep more cash in your pocket.
