Burger King are expanding their menu with a strange new item

So apparently this is all an elaborate early April fools prank, but they have managed to trick most of the internet with their genius marketing.

On Wednesday the fast food giant posted this video introducing 'Whopper Toothpaste', which is exactly what it sounds like.

The idea behind the product is keeping that famous taste that everyone loves in one's mouth while also being able to brush your teeth.

They teamed up with with advertising agency and made a perfectly believable ad that no one thought question.

Nice move Burger King.
