Japan is facing a ninja shortage. There is a high demand for “ninja shows,” but it is a dying tradition, and companies have trouble finding properly trained ninjas.
In 2009, Burger King ran the “Whopper Sacrifice” campaign. They would give a free whopper to anyone who would delete 10 of their Faceboòk friends. Facebòok suspended the program because Burger King started notifying people that they had been removed from a person’s friend list because of a burger.
