Simmons: You ever wonder why we're here?
Grif: It's one of life's great mysteries,isn't it. Why are we here? I mean,
are we the product of... some cosmic coincidence or, is there really a
God... watching everything? You know, with a plan for us and stuff.

Grif: Oh, uh... yeah.
Simmons: What was all that stuff about God?
Grif: Uh... hm? Nothing.
Simmons: You wanna talk about it?
Simmons: You sure?
