The Emperor's New Clothes

( Plot summary from wikipedia)

An emperor of a prosperous city who cares more about clothes than military pursuits or entertainment hires two swindlers who promise him the finest suit of clothes from the most beautiful cloth. This cloth, they tell him, is invisible to anyone who was either stupid or unfit for his position. The Emperor cannot see the (non-existent) cloth, but pretends that he can for fear of appearing stupid; his ministers do the same. When the swindlers report that the suit is finished, they dress him in mime. The Emperor then goes on a procession through the capital showing off his new "clothes". During the course of the procession, a small child cries out, "the emperor has no clothes!" The crowd realizes the child is telling the truth. The Emperor, however, holds his head high and continues the procession.
