Fast food chains started off with serving simple burgers and fries. But as years pass by, more and more fast-food chains are looking for unusual food menu items to add to their list in order to entice their customers and to keep the buzz alive.

From no bun burgers to dippers, from making a sandwich out of donuts to adding bacon on sundaes, here are some of the weirdest fast-food menu items from the last decades.

One of the biggest fast-food chains in the world is KFC, and they started the decade with a bang. In 2010, KFC introduced the Double Down burger, which sandwiched two kinds of cheese, two strips of bacon, and the famous Colonel's Sauce between two boneless chicken filet. What made this creation a "talk of the town" after its release was how unhealthy it was compared to a regular burger.
