Billy West has commented that he is not impersonating Richard Nixon for the role; he is impersonating Anthony Hopkins in Nixon (with "a little bit of werewolf ", his Nixon has a tendency to inject a sound similar to "aroo" into his sentences), and that he, instead of trying to cultivate a good impersonation, cultivates the flaws in his impersonation. Matt Groening also frequently expresses his pleasure that he can continue to poke fun at Nixon 30 or 40 years after he was in office. Nixon's head was included in TV Squad 's list of the five best television appearances by presidents in animated or puppet form. The character was considered to be particularly interesting because he could be "pure evil" but also command respect and also because "Nixon's head trapped in glass is just really funny."
