I can't think of a less suitable environment than a party with children and spouses. They need to find a place to have the children go, and assuming a heterosexual crowd, under the best assumption, about half of the audience won't be very interested in the stripper. And watching a stripper with your parents and grandparents would seem to change the mood entirely.
I have one that's close but, since minor children weren't involved, wasn't as bad.
A male stripper was hired as the director's gift for one of the productions at my college theatre department. The director's gift is always a surprise to the director (as to what it is), but the rumor regarding this one circulated throughout our department very quickly (which must've been without the instructors hearing about it or, I think, they would've shut it down immediately despite the dept being pretty laid back). One of my friends (who was part of the production) brought a camcorder to tape the entire thing. It occurred at school, during the lunch hour break between classes (they never scheduled classes 12pm-1pm) and took place in our smaller theatre (so everyone watching was very close to the stage. The poor director (a female) was told to sit in a chair in the center of the room. I wonder what she must've thought for the theatre to be full of students who weren't even part of the productions (there were some fringe-theatre students in the room as well). Yes, I stayed to watch (I was 22 years old at the time and didn't know better as did several of my fellow theatre classmates and friends who, I'm sure, wouldn't have stayed to watch now). We were in awe that this was actually taking place and wanted to witness how it would go down.
To her credit, the director was a good sport about it and participated but only after she tried to run out of the room and got stopped by the stripper (guts that woman has!). I would've been humiliated to have a room full of students -- MY students! -- watching as a stripper gyrated in front of me, never mind one of my trusted students (and friend) taping it. After it was over, my friend told me the director walked up to her and demanded the videotape (this was 20+ years ago so before the digital age). Friend also told me, later on, that when she encountered the director's husband, he just gave Friend "the look."
After the dance was over, the ringleader (who I suspect came up with the idea) said they "wanted to give her a gift that she'd never forget" (it had no relation to the theme of the play). I still tell that story and just shake my head wondering what in the world they were thinking (it was the actors and my friend who gave the gift so everyone was between the ages of 19 and mid-30s).
