[In a dim alley behind the town square, Molly and Bill rehearse their silly accents for a party heist tonight.] Molly: "Bill, remember the party at the old bakery? The balloons look surprised, and the cake pretends to be innocent." Bill: "Yeah, the kid magnets are buzzing, the parents wearing party hats like helmets. It's silly, perfect for a heist of giggles." Molly: "Our go signal is the piñata cracking, right? When the candy rains, we sweep the presents like unfledged pigeons." Bill: "Unfledged pigeons. I love that. But we need a plan that doesn't wake up the snoopy stuffed animals or the squeaky drumline." Molly: "Quiet as a librarian, brave as a burglar—our first move is distraction, a parade of puppies tipping the attention scale." Bill: "Puppies, huh? We could borrow a cartful of plush canines from a toy store and wheel them in like a furry traffic jam." Molly: "And I’ll wear the chef hat, claim I'm orchestrating a baking booth that nobody eats from, so we sneak through the back." Bill: "Back doors, front doors—both are suspiciously well-lit. We should default to the door that looks bored and ignored." Bill: "Cakes and candy, we leave smiling."
