The myth goes that ID co-founder and programming-guru John Carmack was about to go to sleep when he heard his neighbor's dog barking. These barks allegedly triggered a vivid vision of Hell, engulfing Carmack in a realm of hellfire and brimstone. The dog claimed it's name was "Sam," and ordered Carmack to kill people. Hall's dreams were crushed, however, when John Romero, founder of such popular metal bands as Pantera, Slayer, and REM, who was also a former exorcist and Marine, refused to allow "Tei Tenga" or anything from Hall's holy document "the Doom Bible" to make it to the final game.
