The character of Razor was based on singer/songwriter Tori Amos, who at the time was an unknown, a friend of one of the graphic designers. Amos was the front woman of a hair metal band called "Y Kant Tori Read"; Razor's hair and outfit are identical to the one Amos is wearing on the cover of the "'Y Kant Tori Read' album. Additionally, one potential plot line in the game has Razor inexplicably playing classical music on a grand piano, Amos' instrument of choice.
The "weird Edsel's" license plate reads THX 1138, the title of an early George Lucas film.
