I've told mine before, but I'll tell it again. Happened this year and it's an instant classic. Basically, I called a double foul and the person doing the book obviously didn't know what that was or pay attention to me. So I reported it (both numbers) and she's like "What'd you call" and I said a double foul. And she goes "well that's 5 on her then." And I said no wait, double foul, then I repeated both numbers and we went on.
