Molly spread the crayon map across the van hood while Bill juggled juice boxes stolen from rehearsal. The suburban house glowed with balloons and frantic parents arranging tiny chairs for the birthday ambush. A clown van wobbled past, music squeaking like a trapped goose. Molly tapped the side window on her sketch. "We hit at three during cake." Bill nodded, adjusting his fake mustache which kept drooping into icing sugar from the donut stash. Inside, kids would be screaming songs, distracted and sugar wild, perfect cover for quiet professionals. He peered through binoculars at piles of bright wrapped boxes stacked near the porch table. "Kids cry loud. I hate clowns." Molly grinned, stuffing party hats and a borrowed gift bag into her backpack. The plan needed speed, smiles, and absolutely no magic tricks. She checked her watch, synchronized against the ice cream truck schedule outside. "Grab gifts, run fast, no noise." Bill saluted with a Capri Sun, spilling sticky red across his clown nose disguise. They rehearsed fake names, goofy voices, emergency exits past the bouncy castle. "Deal." Neighbors waved, mistaking them for exhausted entertainers late for setup. Molly winked, pulling on oversized shoes and honked a tiny horn. "Go."
