Molly peered over the hedge and whispered, "Say the plan back to me, Bill." "We dress as clowns, grab every present, and leave." "Why clowns?" "Nobody looks at a clown." "Bill, every child looks at a clown. Usually screaming." "Then we distract them with balloon animals." "Can you make balloon animals?" "I can make one balloon sad." "Unbelievable. Fine, here's the real plan. The magician got a flat tire. I arranged it. We're his replacements." "Do we know magic?" "You'll pull a scarf from your sleeve while I quietly bag the gifts." "What if the kids want a real trick?" "Then you make the birthday cake disappear." "Molly, that's just eating it." "Exactly. Improvise." "What about the parents?" "They'll be filming. Adults never watch the magician, only their phones." "And if a toddler grabs my leg?" "Then you walk with a toddler. Committed thieves accept collateral toddlers." "That's not a rule." "It is now. Ready?" "Wait, is that a piƱata?" "Bill, focus." "It's shaped like a police horse." "Move!"
