the united states also used the short-lived slogan, "tastes so good, you'll roar", in the early 1980s. the tv commercial most known from this slogan involves a young man biting into one of the kit kat bars in a grocery store, and roaring like a lion so loudly the whole store shakes violently, knocking items from the shelves. another short-lived us slogan was "that's what you want", whose television adverts showed people pulling unlikely foodstuffs from their pockets or purses, before rejecting them in favour of a kit kat.
