Zonker: Is that you, Brenner? Zeke: Hey, Zonk! Good to see you again, man! Zonker: Brenner, what the hell is going on? Who had Duke declared dead? Zeke: It had to be done sooner or later, man.

Zonker: As a courtesy to his heirs, no doubt. Zeke: Right. Besides, I couldn't remember which cult he belonged to.
