"Listen very carefully, Bill. We hit the Taylor birthday bash precisely at three when the clown starts his tragic magic act. All the parents will be distracted by the failing balloon animals," Molly whispered softly to him. "Are you genuinely insane, Molly? There are twenty screaming toddlers armed with plastic swords, plus a vicious petting zoo in that backyard. How do we possibly sneak out with a mountain of brightly wrapped building block sets without getting absolutely demolished completely?" Bill sighed deeply, rubbing his temples. "We infiltrate as the elite catering staff. I carry the lukewarm hotdogs, and you carry the triple chocolate cake. When they sing, we stuff those oversized gift boxes directly into our empty plastic ice coolers," she said, tapping the blueprint drawing. "I am deeply allergic to cheap frosting, Molly. And miniature ponies. Plus, what if they demand I make a festive balloon hat? I only know how to twist a pathetic worm," he groaned aloud. "Forget the worm! This is the greatest toy haul of the entire summer season. Timmy is getting a motorized titanium scooter. We desperately need that scooter to pay off our gambling debts. Now help me hotwire this rented ice truck."
