I think everyone should have fun with their job.
But if these "mooners" are intentionally pulling a prank that could harm or threaten a performance, such as trying to make Eden break character and/or laugh during a show... as well as potentially having children in the audience who weren't expecting any form of nudity suddenly being in on this private joke...
You apparently still have no idea how that could screw up your whole career.
The worst-case scenario?
Eden laughs or stumbles on a lyric during the song. Everyone backstage laughs and thinks it's so funny.
If the stage manager, musical director, or Equity deputy knows why or what happened, probably at the very worst, Eden would be given a friendly reminder to do her best to stay focused, but since this was her last show, and clearly was a surprise to her, I doubt anything would be said to her about it at all.
As far as the mooners go.. .The Equity deputy (again in a worst-case scenario) could report them to the union. Fines could be issued. If an irate parent in the audience complained about their small child seeing a naked butt in the wings? Then you could have a potential legal case against the producers of the show. They would very likely fire the actors involved in the prank immediately, and if it got into the media, they would also have to issue a statement about their stance on such behavior. This is a "family show" remember?
Again, I'm not making this stuff up... I've seen similar "jokes" result in this kind of outrageous tailspin...
So the next time any of you are thinking of horsing around in the wings? Stop and think first. Is it worth it? Could I lose my job from this?
Just some friendly advise from someone in the trenches who's seen a lot of stuff happen.
