Molly and Bill crouched behind a plastic slide shaped like a grinning dinosaur, the backyard party pulsing with shrieks and off-key singing. Balloons bobbed like colorful surveillance blimps. “Think the clown’s got nunchucks?” Molly whispered, eyeing the birthday boy’s hired entertainment. Bill snorted. “Only if the piñata fights back. We wait for cake. Kids go feral, parents get distracted, we swoop in like budget ninjas.” Molly adjusted her glittery party mask that read “It’s My Birthday Too!” in sparkly letters. “I still say we should’ve worn the mascot costumes. Nobody suspects a six-foot teddy bear stealing gift bags.” “Last time the zipper jammed and I spent twenty minutes hopping around like a depressed kangaroo,” Bill muttered. “We stick to the plan. Grab the table, shove everything in the trash bags that say ‘Happy Birthday,’ and vanish before they sing again.” “God, not the singing,” Molly groaned. A sudden cheer erupted as the cake appeared, candles flickering like tiny escape signals. Bill cracked his knuckles. “Ready, partner?” Molly flashed a wicked grin beneath the mask. “Let’s go ruin some childhoods. Elegantly.”
