"Okay, Bill, run it back," Molly said, tapping the crayon map. "We go in as clowns." "Nobody hires two clowns, Bill." "Budget cuts. We say one of us is the understudy." "And the presents?" "Stacked on the gift table by the bouncy castle. Forty, maybe fifty boxes. Little Timmy's turning seven." "How do we get fifty boxes out?" "Balloon animals. I make a giraffe, everyone looks up, you grab the loot." "You can't make a giraffe." "I can make a long balloon. Context does the rest." "What about the mother? She's got eyes like a hawk." "That's why we bring the piƱata. Stuffed with confetti." "Bill, why would confetti distract her?" "Have you ever cleaned up confetti? She'll be gone for hours." Molly rubbed her temples. "And the getaway?" "Ice cream truck. Borrowed it from my cousin." "Does it still play music?" "Only 'Greensleeves.' On loop. Can't turn it off." "So we're escaping at eleven miles an hour, broadcasting our location?" "Nobody suspects the ice cream man, Molly." "Everybody suspects the ice cream man, Bill." Bill paused, then brightened. "Fine. We steal the bouncy castle too. Deflated, it fits in the freezer." "Bill, that's the worst plan you've ever had." "You said that about the petting zoo." "We got arrested by a goat."
