When Americans look back at the decade called the "Aughts," they will ask: "Why 'Aughts?' Didn't we spend the past ten years calling them 'The Ohs,' as in 'oh-four?'" Then Americans will think about Christmas because it's that time of the year. Most of all, they will never forget the tragedies of the past ten years: special promotional nachos from Taco Bell.

We count down the three worst Taco Bell nachos disasters of the '00s. Brought to you by Del Taco. 

3. iNachos (2007) 

Eager to cash in on the Apple iPhone and iPod, Taco Bell unveiled the iNachos. Nacho users built on top of crispy corn tortilla chips by purchasing individual nacho apps like guacamole and cheese. The iNachos quietly disappeared in 2009 when Taco Bell was successfully sued by the town of Inachos, Greece for infringement.

2. Blue Nachos (2003) 

Following the success of Pepsi Blue, Taco Bell introduced Blue Nachos, nachos that are blue. Due to last-minute market trend research, the Blue Nachos were relaunched as Texas Hold 'Em Poker Nachos. That lasted a few more years.

1. The Four Feathers Movie Tie-In Chicken Nachos (2002) 

Did someone call Harry Feversham (Heath Ledger) a chicken? Well, you are what you eat, because Harry loves chicken! You would, too, with the Taco Bell Four Feathers Chicken Nachos, topped with grilled chicken and chicken bacon. Was as popular as the movie. Loosely based on the A.E.W. Mason novel.
