In The Addams Family (1991), Gomez Addams calls Sally who is on the TV Show,
But she rejected his call with the words:
Mr. Addams, please stop calling. We do not know where they meet.
Why did she reject the phone call from him?
The TV was showing a daytime programme where someone was being interviewed with the question:
So your son was brainwashed by voodoo slave masters and forced to recruit others. Let's take a call.
The joke is that Addams was supposed be be interested in that spooky type of activity and was constantly calling for more information even though, in the real world, no-one would believe such an outrageous claim.
