You do realize that the original Shakespeare and similar time period plays were MUCH more like how the kids did it, right? Plays in that century were bawdy, vicious, and just nuts. And to be fair, Shakespeare's own material talks about stuff, if modernized, would be considered rated 'R'.

Sitting quietly to watch a show is pretty recent. Even classical performances were louder with praise and en-core requests shouted out loud.

I'm not exactly sure when the 'sit down, shut up, and listen' happened, but yeah.
