Maybe you have a list as long as your arm of movies people have suggested you make, but here's one more!
How about a teacher at a finishing school, teaching students how to control their bladders? It either be an instructional video or a fly on the wall watching the teacher at the front of the classroom, with the teacher drinking and holding while explaining her techniques. I think it could be filmed with or without a student in the video.
You'd need a composed and confident model - I'd always thought Carissa would be perfect but Candle is impressive in that respect as well.
