All humans are vermin in the eyes of Morbo.

Quote
Morbo: "Morbo will now introduce tonights candidates. Puny human
number one, puny human number two and Morbo's good friend
Richard Nixon."
Nixon: "Hello Morbo. How's the family?"
Morbo: "Belligerent and numerous."
Nixon: "Good man, Nixon's pro-war and pro-family."
