Since drinking parties and poker games that attract the same size of group are allowed, just keep some beer bottles and decks of cards around the house for the members to grab as props if the police come a knocking to enforce this.
Reminds me of the story about the elementary school teacher who hears suspicious sounds coming from the boys’ bathroom and goes in to investigate. She finds several little boys all down own one knee in a circle. In a loud voice she demands “And just what’ going on here????” There’s a lot of hemming and hawing and finally one of the kids sheepishly admits their shooting craps. The teacher seems quite relieved and says “Oh OK, just so long as you aren’t praying!”
How about a lady-er-um-woman jumping out of a cake?
