Molly smoothed out the crayon-drawn map on the hood of their dented van. "The bounce house inflates at noon, Bill. That is our zero hour." "Are you insane, Molly? Timmy is turning seven. Seven-year-olds are utterly feral." "Stick to the layout. The primary gift table sits directly between the unicorn piƱata and the juice station." "What about the mother?" "Brenda? Neutralized with a forged coupon for half-priced boxed chardonnay down the street." "Brilliant plan. And my cover?" Bill nervously adjusted his plush beaver ears. "You are Barnaby the Juggling Beaver." "I despise rodents, Molly. Plus, I cannot juggle." "Then balance a plastic teacup on your nose and distract the toddlers while I sweep the Lego sets into our tactical diaper bag." "And the backyard perimeter guard?" "Uncle Gary guards the cake, but he always passes out cold after three bratwursts. We bag the drone, the pony, and the slime kits, then exfiltrate through the doggy door." "What if that terrifying clown spots us?" "Bribe him with frosted animal crackers. Did you pack the smoke pellets?" "No, but I brought two high-velocity glitter bombs." "Perfection. Synchronize watches. At twelve-fifteen sharp, we strike hard." "For the birthday loot, Molly." "For the birthday loot, Bill."
