Your Signal Peeves?

[Freddy]

What are your non-Fed signal pet peeves?
I wonder where the "upward circling finger" when a free throw fails to hit the rim came from?
I scratch my already bald head when one's signal for a block looks more like a chicken dance than that faceless guy at the back of the book.
I grimace when, while reporting a "push" during rebounding action, a person does some kinda imitation of an old George Reeves superman.
I, as one observing a game, always note the confusion that sometimes occurs when an offical signals a time-out to the table using a "T" motion.
Are there any that you find either annoyingly obnoxious or frustratingly frivilous?
