It began with the creation of the great cable providers. Many were given to the people of the US, but they were all of them deceived. In the land of Mordor, in the fires of Mount Doom, the dark Lord Sauron forged in secret a master cable provider, to control all others and into, he poured his cruelty, his malice, and and the worst fucking customer service imaginable, its name was Comcast. One by one respectable cable providers fell to the power of the Comcast. But there were some who resisted. A last alliance of Disgruntled customers and AT&T employees marched against the tyranny of Comcast and in the parking lot of Comcast's headquarters they fought for the right to choose a respectable cable service.
Comcast must be destroyed before its evil consumes the world.
