The kids are’nt the one who organized the event or set the agenda for fun and games or who bought the pinata, it was most likely an adult and either an employee of UM or the school the children attend and I would bet a dollar to a donut they knew exactly what they were doing.(My wife just got back from the donut store and that would be ten dollars to a donut, as a kid I bought donuts 3 for a dime.)
It's hard to find good hula dancers.
