You must listen to Dead Kennedys - Holiday in Cambodia when reading this, it's a necessity.
Diamond Tiara sold out Ponyville. She funded and gave helpful political secrets to a communist party called the Khmer Rouge. They quickly gained the upper hand and soon enough Equestria became enslaved by armed soldiers working for a cunning but undeniably evil dictator. Diamond now continues to live the glamorous rich girl life she never lost, but even the smallest victory for the civilian prisoners of Ponyville will cause her downfall.
I don't own the song Holiday in Cambodia, it belongs to Dead Kennedys and Alternative Tentacles. I also do not own the cover for the single, please don't sue me.
