In honor of the Whopper's 55th Anniversary, Burger King is introducing "new" limited-time menu items to the line-up. Yes, this is essentially a burger birthday. Priorities, baby.

The items will be available nationwide and presented in old-school packing meant to reflect the commemorative occasion. Among them, the Wisconsin White Cheddar Whopper Sandwich -- a beef patty topped with smoked bacon, 'Wisconsin' white cheddar cheese and all the obligatory veggies. Of course, the main player here is the Angry Whopper Sandwich that gets it's delicate name from the melted Habanero cheese, slices of jalapeño, spicy onion petals and angry sauce. Both sandwiches start at a suggested retail price of $4.49.

Of course, BK would probably suggest you pair any of the limited-time sandwiches with their equally limited Seasoned Sweet Potato Curly Fries. Claimed to be served hot and fresh daily, this item is described as a "twist" on your regular ol' sweet potato fries. Clever wordplay lols and twisty nomz go for a suggested retail price of $1.89. Although, in terms of the Angry Whopper, we're not too sure how "new" it really claims to be -- its original debut in the US dates back to 2008. To give them credit, the original contained pepperjack cheese and "Angry" onions, instead of today's Habanero cheese and spicy onion petals. Admittedly, we're nitpicking here but hey, we're not the ones celebrating a burger's birthday.
