Chocolate Whopper? Burger King creates 'gag' commercial for April Fools Day

It's Easter, but it's also April Fools Day, and many corporations are inventing gags and pranks to join in on the fun.

Burger King has posted a video announcing the Chocolate Whopper, which boats a chocolate cake bun, raspberry syrup instead of ketchup, vanilla syrup instead of mayonaise and white chocolate rings instead of onions.

And that's not all. T-Mobile is introducing a "smartphone shoe," which comes with a smartphone stick for "really flexible people," and Auntie Anne's is promising to start making pretzel-scented essential oils.

The products, of course, are just a joke, but it's all in good fun.
