Molly and Bill huddled in the bushes near the community center where the children's party was in full swing. Laughter and music filled the air making their break in seem like a scene from a slapstick movie. They had spent days planning this heist targeting the mountain of presents stacked in the corner of the hall. With their clown outfits packed in bags they felt ready for anything if stealing from kids. The absurdity of the job was not lost on them but the thrill kept them going. "We go in during cake time" Molly said. "Yeah kids love cake" Bill replied. The pair had mapped every detail from the timing of the games to the position of the adults. Molly would distract the crowd with her balloon skills while Bill made off with the goods in a sack. They imagined the parents confusion and the children's fun despite the missing gifts which in their logic seemed acceptable for a comedic heist. As they adjusted their wigs and noses the two thieves shared a laugh about how this might be their memorable score. "And remember no candy for us" Molly added. "Right only the presents" Bill confirmed.
