"Right, the plan is simple," Molly whispered, tapping the blueprint. "We slip in through the bouncy castle vent, grab the presents, and leave before the clown finishes his balloon animals." "Balloon animals?" Bill squinted at the map. "Molly, that clown scares me more than the security guard." "Focus. The gift table is by the piñata. Nobody watches the piñata." "Nobody watches the piñata because it's a donkey stuffed with candy, Molly. That's not security, that's a distraction." "Fine, but I need you to grab the big box with the bow. The one shaped like a pony." "Why do I always get the pony?" "Because you're the only one who can fit through the ball pit without sneaking in a sock." "That was one time." "It was three times, and the birthday girl still remembers your face." "She waved at me, Molly. That's basically friendship." "She waved because you were carrying her grandma's sweater. Now shh, the music's changing." "Is that the Hokey Pokey?" "Bill, it's always the Hokey Pokey. Everybody's distracted doing the Hokey Pokey. Go, go, go!"
