In the dusty back room of an abandoned storefront they used for planning, Molly sat cross-legged on an old crate while Bill paced between stacks of cardboard boxes that once held previous loot. Balloons from a deflated experiment floated near the ceiling as they finalized the details of their most cartoonish robbery yet. Maps of residential blocks and photos of a decorated patio covered the floor. Their goal was simple: invade a children's birthday party and steal every present that sat waiting for little hands. They knew the job required perfect timing and lots of humor to throw the adult hosts off the scent of any suspicious activity happening right under their noses at that lively party. "We arrive as the surprise entertainers with full clown makeup so no one recognizes our faces later," Molly said with a belly chuckle. "I can disguise as the cake delivery guy and then change into a magician behind the shrubs," Bill provided. "Will the presents be easy to spot? Usually they sit near the food table or under a special tree decoration," Molly questioned. "From the photos yes and we can use a large empty piƱata to fill with them as we walk about free," Bill replied. "Great. Then the diversion will be me starting a bubble blowing contest that gets every kid yelling for more," Molly planned. "And I will do a fire ball trick with birthday candles carefully so parents scream a little scaring alerts," Bill continued. "Entry is through the unpacked side fence that is loose. We leave by the front as if packing our props up early," Molly outlined. "If we get stopped we claim the kids already opened them and we are collecting wrappings," Bill thought. "Perfect, and to keep it comic we leave stickers that say thank you for the donations to the clown charity," Molly laughing concluded. "Yes that seals the joke. No real damage done just a surprise punchline for everyone there," Bill confirmed. "We could use the game of pin the tail to get kids to the other side of the yard," Molly added. "Yes meanwhile I bag the gifts carefully to avoid tearing paper," Bill said. The pair then spent the remainder of the evening arguing playfully over who got to wear the louder shoes and which presents to nab first if they had to choose under pressure. They practiced their entries and exits before covering maps with red pen marks for each stage of the operation. Molly practiced juggling three rubber balls to look skilled. Bill demonstrated a disappearing scarf that flipped into creating a hidden pocket. Their laughter bounced off the walls until late. With every contingency covered from sudden rain to unexpected guest numbers the plan stood ready to deliver laughs and loot in equal measure. Ready for the next day scouting run, they finally rested smiling at their genius. They went over the whole sequence one last time to memorize every cue and escape route. Molly made a list of required items including face paint and big red noses. Bill checked the weather for the next Saturday.
