Putting a period in the place of a question mark is a bold statement. Example: What the hell? vs. What the hell. That's a pretty clear example. Another: Where's my money? vs. Where's my money. See? The period creates an entirely different emotion than does the question mark.

It works reciprocally. Example: My bag is on the ground. vs. My bag is on the ground? The period creates a statement of truth. The question mark inherently denies truth. Another: I ate the last olive. vs. I ate the last olive? In this case, the question mark creates a vision of a buffoon who doesn't know his left from right or up from down. The period creates certainty. And tampon sales.
