Damn straight. It's a nice change to have a mum that's pretty much a whore (or at least was one) with attitude and whatnot rather than the same old same old nicey-nicey mums in almost every other cartoon out there (see: Simpsons, King of the Hill, Family Guy, etc).
Still yet to see the dad shake the cliché of idiot father, but then, I'm not sure if it would really work out.
