I know what you're thinking. "It's too good to be true." Well, it's happening.

Burger King is giving you the chance to get a Whopper for just ONE PENNY. But BK is playing a bit dirty with this deal.

Here's how it works . You have to download the new Burger King app and place the order within 600 feet of a McDonald's location.

Burger King is calling this "The Whopper Detour" and take advantage because it is only available until December 12th.

But man BK -- troll McDonald's much? And during the holiday season? Man, talk about salty.
