"Right, the plan's simple," Molly whispered, tapping the blueprint. "We slip in through the bouncy castle vent, grab the presents, and be out before the cake gets cut." "Simple? Molly, there's a clown at the door." "Clowns don't count. Nobody's scared of clowns." "I am. Look at his shoes. Those are war crimes." "Focus, Bill. Three hundred pounds of gift-wrapped loot. Tricycles, a robot dog, a drum kit." "Why would a six-year-old need a drum kit?" "Exactly. Justice for the drums." "And what if the birthday boy catches us?" "We bribe him. I brought a fistful of sherbet lemons." "Sherbet lemons? Molly, that's not a bribe, that's a snack." "Fine. Plan B is the piƱata. We swap it for a wrapped box of socks." "You've thought about this too much." "Only because I have a spreadsheet, Bill. Now shush, the magician's about to pull a rabbit out of a hat." "Oh no. Bunny's on the list too."
