Hidden behind a row of neatly trimmed hedges, Molly and Bill watched the children's party with keen eyes. The event was in full force with games, laughter, cake and of course the impressive stack of presents waiting to be taken. After their last heist went bad they had decided a change of pace was necessary and what better way than to target something so unexpected. The duo had mapped out their approach from every angle making sure they knew the layout and the schedule of events. Molly would pose as the assistant to the magician while Bill took on the role of the main entertainer with his awkward juggling skills that were sure to captivate the young crowd. They figured the parents would be too busy chatting and taking photos to notice anything amiss until it was too late. The sack for the loot was hidden under Bill's baggy clown pants and the getaway car was idling a block away with the engine running low. It was now or never for the pair of bumbling thieves as the party reached its peak activity level. "You create the diversion," Molly said to him. Bill nodded and replied, "I distract the kids with my dance then you grab every present you can."
