“Bill, are you sure this is the party?” “Unless the diamond gala has recently replaced champagne with fruit punch, yes.” “Then why are we stealing presents from children?” “Because the adults guard the cake, Molly. Presents are unattended.” “They’re wrapped in cartoon paper.” “Excellent camouflage.” “That one says ‘Happy Birthday, Trevor.’” “Trevor won’t miss it.” “Trevor is six.” “Then he’ll forget by Tuesday.” “Molly, stop judging and hand me the invitation.” “This says ‘Trevor’s Dinosaur Adventure.’” “Exactly. We’ll blend in as dinosaurs.” “We’re wearing black turtlenecks.” “Silent dinosaurs.” “You planned this robbery with a crayon, didn’t you?” “Only the floor plan. The crayon was surprisingly detailed.” “Why is there a drawing of a volcano?” “Security feature.” “That’s the bounce house.” “Even better. Perimeter surveillance.” “Bill, the presents are guarded by a toddler.” “Is he armed?” “With a juice box.” “Juice stains are permanent. Retreat.” “We can’t retreat. The clown has locked the front gate.” “Why?” “He says nobody leaves before the magic show.” “Then we steal the magic show.” “Molly, that is not a present.” “It disappears, doesn’t it?” “Fine. New plan: we perform, distract everyone, and exit empty-handed.” “Empty-handed?” “With dignity.” “We lost dignity when you hid behind the piñata.” “Quiet. The piñata knows too much.” “Bill, are those sirens?” “No. That’s the birthday song.” “Then smile.” “I’m smiling.” “You look constipated.” “I’m improvising.”
