Molly and Bill were positioned in a hidden spot not far from the bustling children's party that was taking place in the large backyard of the suburban home. They had been watching for some time now. The sun was shining brightly and various party games were in full swing with kids chasing each other happily. "Bill, we're stealing all the presents from that children's party today," Molly whispered. Bill looked at her with surprise. "Molly is that really our plan? It seems kind of mean to the kids." She rolled her eyes at him. "Mean or not we need the money from selling those toys." He scratched his head thinking. "Okay but how do we get inside without being noticed by anyone?" "We disguise ourselves as clowns and join the fun activities," Molly replied with confidence. Bill nodded slowly in agreement. "Then while they are distracted I will take the presents." "And I will create a diversion with some silly jokes," she said. "Yes and then we run to the van with the loot," Bill replied. "This will be our funniest heist ever done," Molly said smiling. After finishing the discussion they got their costumes ready for action.
