Bill adjusted his tactical binoculars, squinting through the windshield of their rusted surveillance van. Across the sunlit suburban street, the seventh birthday party of little Timmy was in full swing. A mountain of brightly wrapped presents sat unguarded upon a folding table. It was the perfect score. Molly spread out a poorly drawn crayon map over the dashboard. Her black turtleneck was covered in rogue glitter from their previous reconnaissance mission. She tapped a fingernail against a smudge representing the designated gift zone. "The bouncy castle perimeter is notoriously weak." Bill wiped a bead of sweat from his forehead. He had spent three years infiltrating high security bank vaults, but children terrified him. "Are the toddlers armed?" Molly rolled her eyes and folded the schematic. "Only with sticky hands." She grabbed a grappling hook and a large paper horse costume. "I brought the wet wipes." He nodded firmly, strapping a plastic sword over his shoulder to blend in with the pirate theme. They stepped outside. The operation was a logistical nightmare involving tiny civilians fueled entirely by refined sugar. They crept behind the bushes, preparing to snatch every last toy under the guise of a brutal game of musical chairs.
