"Right, Bill, here's the plan. We slip in through the bouncy castle vent, grab every present with a bow on it, and be out before the clown finishes his balloon animals." "Hang on, Molly. Why do we need the vent? The front door's wide open. Mrs. Pickering's been yelling about the ice cream for an hour." "Because the front door has a seven-year-old guarding it, Bill. Tiny lad, pirate hat, carries a plastic sword." "Pirate hat? That's a serious threat." "Deadly. Now, the tricky bit is the piñata. Nobody touches the piñata." "Why not?" "Because I'm not explaining to a crowd of toddlers why a sack of sweets fell out of the sky onto a grandad." "Fair point. What about the cake?" "Cake is off limits. Sticky fingers leave evidence." "And if the clown spots us?" "We wave, we smile, and we hand him a balloon. Nobody suspects a clown." "Molly, I'm starting to think this is the worst heist ever." "Relax. Tell me again how many presents we're taking?" "Forty-two." "Perfect. Let's go steal some birthdays."
