A prop doesn't and A cove has no water. A running crew rarely gets anywhere . A purchase line will buy you nothing. A trap will not catch anything. A gridiron has nothing to do with football.
Strike is work.
And a green room, thank God, usually isn't. And lo' we the tech's build the set and hang the lights and cue the sound and fly the drapes and build a wonderful show. Some actors claim that techies aren't important. None, if it was working once, they know better than to mess with it. The lights have a flashback to disco.
