El Paso, (Entravision). Get Ready For Whopper Toothpaste … Adweek magazine claims Burger King France is promoting a Whopper toothpaste. The 60-second ad says; “The Whopper toothpaste soon [be] available in your restaurants and drugstores which means you won’t have to hesitate between enjoying a Whopper and brushing your teeth ever again.” The magazine claims the commercial is most likely an early April Fool’s Day stunt.
