For hamburger aficionados who want the smell even when they can't get a bite, Burger King is putting the scent into a limited-edition fragrance. Burger King said Friday that the Whopper grilled beef burger-scented cologne will be sold only on April 1, and only in Japan. Sounds too good to be true? It's not an April Fools' Day joke, though the company chose the date deliberately. The limited "Flame Grilled" fragrance can be purchased at 5,000 yen (about $40), including the burger. There will be only 1,000 of them. Burger King says it hopes the scent will also seduce new grill-beef burger fans. (More Burger King stories.)
