The main problem here is what the audiences wish to see and hear (what they expect) and what is possible in the real world. It isn't necessarily right that the filmakers get it wrong, but that when they get it right, the audience runs from the theater.

Case in point, there have been many experiments in big budget films to try and record things as they actually occured while filming. Usually something like 80%, including dialog, is recorded after the fact, in the studio. One film (I think it was Barry Lyndon) used real on-set recordings to film battle scenes, having the sound arrive seconds after seeing the smoke from the guns and cannons. The test audiences simply couldn't get their heads around the discrepancy, and so it was changed to showing the shots and sounds simultaneously.

The same audience disconnect would be applied to #6 above as well (if you slowed down the voice, the audience would go, "Huh?"

When I first saw this headline, I thought it said, "clap your testicles" and I just thought, "Ouch!"

Could be even more interesting if they called it "Bitch and Pussy".
