A little more than a year ago, Taco Bell created shells out of Doritos Chips. This was a milestone in their endless quest to invent unexpected combinations of melted cheese, mystery meat, crunchy shell, and the most wilted lettuce to grace this green earth. Taco Bell titled this creation "Doritos Locos Tacos."

Taco Bell kicked off the year by teasing its Facebook fans with a photo of a taco alongside a bag of Cool Ranch Doritos over the caption "anything could happen in 2013" — the wink being that Cool Ranch-flavored Doritos Locos Tacos were in the offing.

Last month, the 6,200 residents of Bethel, Alaska, got their collective hopes up after news spread that a Taco Bell restaurant was opening in town.

Taco Bell announced last Friday that its Doritos Locos Tacos — that's a taco with a nacho cheese-flavored Doritos shell — has been sold over 100 million times in the last 10 weeks, becoming the company's most successful product launch ever.
