Molly and Bill hid behind the fence surrounding the bustling children's party, their faces painted with bright colors to blend in as clowns. They had been planning this caper for days, laughing at the ridiculousness of stealing presents from innocent kids at a birthday celebration full of cake and games. The stack of wrapped boxes taunted them from afar, each one potentially containing valuable items or at least stuff they could sell quickly. Bill double checked their tools which included large sacks and a small ladder for climbing if needed while Molly kept watch for any approaching party guests or nosy neighbors who might ruin their fun. The timing was crucial as they needed the kids to be fully engaged in a game or the cake eating portion of the schedule to minimize the risk of being spotted during the actual theft. With everything ready they exchanged a final look before moving into action with their comedic heist about to unfold in hilarious fashion. "Are you sure this plan will work?" asked Molly. "Yes let's go steal all the presents from the children's party now immediately," replied Bill. They took a deep breath and then stepped forward into the chaos. (The scene totals 200 words with exactly 20 words of dialogue.)
