Deep in the shadows of their beat-up old van parked across the street from the loud and chaotic children's party filled with bright balloons and loud laughter, Molly and Bill were carefully finalizing their most ridiculous plan yet for the ultimate heist of all time. Molly adjusted her colorful wig with determination while a very nervous Bill looked increasingly worried about the whole crazy idea they had come up with. "This is our big score," said Molly confidently. "We'll crash the party disguised as extra clowns." Bill frowned deeply with concern. "But what about the kids? They scare me more than cops." "Relax. We wait for the piƱata to break, then swoop in on the presents," Molly assured him calmly. "You distract with bad jokes and I'll bag the goods." "Okay, but I want the video game and the toy robot," Bill negotiated eagerly. "And how do we escape without them noticing us at all?" "Simple. Through the back fence into the alley. No one will suspect thieves at a birthday bash," she explained with a laugh. Bill sighed deeply in resignation. "This better work. Last heist was a disaster with those angry ducks chasing us for miles."
