“Molly, why are we robbing a children’s party?” “Because, Bill, invitations say ‘bring a gift,’ and our budget says ‘bring a spoon.’” “We’re stealing presents from toddlers?” “From the gift table. Toddlers are terrible witnesses; they can’t pronounce ‘felony.’” “That’s not reassuring.” “Relax. I’ve mapped the venue: cake table, balloon arch, presents beneath the dinosaur banner.” “What’s the exit?” “The bouncy castle.” “You want to escape through a bouncy castle?” “Can you think of a less suspicious getaway?” “A clown car.” “Excellent. You drive.” “I refuse to drive anything with painted eyelashes.” “Then we’ll use the piñata.” “As transportation?” “As camouflage. You hide inside, I carry you out.” “I’m six-foot-two.” “Then crouch.” “I have knees, Molly, not accordion hinges.” “Fine. I’ll be the magician.” “Your magic trick is making wallets disappear.” “Exactly. Professional consistency.” “What about the children?” “Give them balloons.” “Empty balloons?” “Children love potential.” A siren chirped outside. Both froze. “That’s the police!” “No, Bill. It’s the ice-cream truck.” “Same audience?” “Different uniforms. Grab the presents.” “Molly, these packages are labeled ‘For Emma.’” “Then we’ll finally know Emma.” “You’re a menace.” “And you’re carrying unicorn wrapping paper.” “Occupational hazard.” They sprinted toward the party, arguing over largest bow.
