Formal fallacy

basically the woman says to him, how do you know this is true? And he says, like all good scientists that follow the scientific method, how do you know it's not true? And as you and I all know, that is the answer to any question.

How can you prove this? And the rebuttal should always be, how can you disprove it? How can you disprove it? That's not a logical fallacy.

Oh, wait a minute.

It's like the definition.

That's crazy.

So, yes, Dr.

Logical Fallacy says, I know all this.

And everyone's like, tight.
