I guess I'm in the minority here, but Ben, I think you're in a no-win situation. If you do it in a way that people can actually hear you, I think that people might find it disruptive. If you, as a member of the lay public, are doing something that might need to get edited out, I might re-consider doing that thing. If you're doing it at a time when everybody's doing it or at a time when no one can hear (like during applause), then not much is gained by doing it.
The last thing you want is for people affiliated with the show to think, "Who's that weird guy in the balcony who keeps shouting, "Scaryotypes"?"
"What was the name of that cheese that I like?"
"you can't run away forever...but there's nothing wrong with getting a good head start"
"well I hope and I pray, that maybe someday, you'll walk in the room with my heart"
