What's with Barbrady and the Mayor?

Are they lovers? And is the Japanese Mafia somehow involved?

The reference is to the scene in Haloween when Chef tries to get the mayor to do something about the zombies:

	[City Hall]
	Chef bursts into the Mayor's office.
Chef:	Mayor, we've got a big problem.
	There is a pile of money on the Mayor's desk.
	Barbrady is presently wearing a garter and fishnet stockings.
	Mayor McDaniels stands up, her blouse in disarray.
Mayor:	Uh, why, why Chef. What a surprise.
Officer Barbrady:	You're probably wondering why we're standing here with
a pile of money and no pants on.
Chef:	Actually, uh�.
Mayor:	Well, I can assure you that it has absolutely nothing to do with the
Japanese Mafia.
Officer Barbrady:	Not a thingy-dingy.
Chef:	I don't really give a crap. We've got to do something about the living
dead!
Mayor:	You mean, Tina Yothers?
	Barbrady and McDaniels laugh.
Chef:	No, damn it. I'm talking about the zombies that have taken over South
Park.
Officer Barbrady:	Well, Evel Knievel, why don't you jump over them with
your rocket cycle?
	Barbrady and McDaniels laugh.
Chef:	Ahh, the hell with you both.
	Chef leaves the office.
Mayor:	Well, let's get back to it.
Officer Barbrady:	Righty-o.
	Mayor McDaniels lies down behind the desk.
