A Dialogue

Oliver: So you're telling me you know how to change the oil in your car?

Gene: That's what I'm telling you.

Oliver: And you're telling me you have had no professional training in oil-exchanging?

Gene: Yup.

Oliver: Impossible!! I'm calling your bluff.

Gene: Call it then.

Oliver: I just did. BLUFF!!

Gene: That's not really "calling my bluff," that's more just saying the word "bluff" really loudly.

Oliver: No, that's actually calling it. I called out your bluff.

Gene: No, you don't understand. You didn't call out my bluff. You just called out "bluff."

Oliver: I don't think you get how bluff-calling works. That's all that is required, me "calling your bluff." Bluff has officially been called. End of story.

Gene: No, no, no. You can't just say "I'm calling your bluff," you actually have to do it. You can't just announce, "I'm doing something right now" when you aren't doing anything. A bluff-call has not happened yet.

Oliver: What are you talking about? Bluff-calls happen when you bluff-call. There is nothing else to it. What else is involved in bluff-calling?

Gene: You call my bluff.

Oliver: I don't even know what that means anymore.

Gene: Exactly.
