Throw what look like a used condom into the 2nd school.
I say "used" because I don't want you to actually use it, just stretch it out and put in a little mayonnaise into the end of it.
Come into the Hall early and put a sexy bra and or panties onto the top of the blades of the ceiling fan so that when they are turned on they will fly off into the audience.
You get the point, illicit sex in the kingdom hall theme.
