A more overlooked wordplay, "Motor Ed," is a cultural reference to the band "Motorhead," a popular, vogue heavy metal band bearing many proportionatenesses with the character "Motor Ed" himself; most notably, he was modelled visually after lead Lemmy Kilmister (his archetype, if you will). An interesting sidenote is that "Ed" can serve as a suffix to "Motor;" that is, to compose the word "motored," but this is, in all likelihood, insignificant.
