The three of them all pointing in different directions made me think about that scene from The Wizard of Oz where Dorothy meets the Scarecrow and doesn’t know which way to go:
Dorothy: Now which way do we go?
Scarecrow: Pardon me. That way is a very nice way…[pointing]
Dorothy: Who said that?
[Toto barks at the Scarecrow]
Dorothy: Don’t be silly, Toto. Scarecrows don’t talk!
Scarecrow: It’s pleasant down that way too!…[pointing in another direction]
Dorothy: That’s funny. Wasn’t he pointing the other way?
Scarecrow: Of course, people do go both ways [pointing in both directions] That’s the trouble. I can’t make up my mind. I haven’t got a brain. Only straw.
Dorothy: How can you talk if you haven’t got a brain?
The Scarecrow: I don’t know. But some people without brains do an awful lot of talking, don’t they?
Dorothy: Yes, I guess you’re right.
