Molly leaned against the van, cracking her knuckles like she was about to rob a bank instead of a birthday party. "Bill, run it by me again," she said. "The plan. The genius plan." "We go in dressed as clowns," Bill said, adjusting a rubber nose that made him look deeply unwell. "Nobody questions clowns." "Nobody questions clowns who show up empty-handed either. We need balloons. Balloons say 'trustworthy.'" "Fine. Balloons. Then we do the magic show, distract the kids, and while they're watching me pull a rabbit out of a hat—" "You don't have a rabbit." "I have a sock. Same energy." Molly rubbed her temples. "And while they're watching your sock, I grab the presents from the table and we walk out the back." "Exactly. In and out. Twenty minutes, tops." "Bill, there's a bouncy castle. Bouncy castles have witnesses. Small, sticky, screaming witnesses." "They'll think it's part of the show!" "There is no show, Bill! There's a sock!" Bill honked his rubber nose thoughtfully. "Okay, new plan. We just tell them we're the DJ." Molly stared at him. "We don't have a DJ booth." "We have your phone and a speaker." She sighed, already reaching for the balloons. "Fine. But if this goes wrong, the sock is your alibi."
